Identification (by Infrared Absorption Spectroscopy)
----------------------------------------------------
Record the infrared absorption spectrum of a potassium bromide dispersion of the
sample. It exhibits bands only at the same wavelengths as that of a spectrum of
a similar preparation of WIN 65489 reference standard. A typical spectrum is
attached.
Chromatographic Impurities (by High-Performance Liquid Chromatography)
----------------------------------------------------------------------
Liquid Chromatographic Conditions
---------------------------------
Using appropriate high performance liquid chromatographic equipment, a suitable
chromatogram is obtained using the following conditions:
Column: Zorbax Phenyl, 4.6 mm x 25 cm (available from MAC MOD Analytical
Inc.) or equivalent
Mobile Phase: Acetonitrile-water-phosphoric acid (85%) 510:490:0.4
Flow Rate: About 1.0 mL/min
Detection: UV at 247 nm, sensitivity 0.02 AUFS
Temperature: Ambient
Standard Preparation
--------------------
Accurately weigh approximately 25 mg each of WIN 65489
Reference Standard and the following reagent standards into a 100 mL volumetric
flask:
WIN 61836, 3,5-dimethyl-4-[[3-(3-methyl-5-isoxazolyl)propyl]oxy]benzamide
WIN 62058, 3,5-dimethyl-4-[[3-(3-methyl-5-isoxazolyl)propyl]oxy]benzoic acid

63843-AS-204.00 -3 of 6-
Dissolve in and dilute to volume with acetonitrile. Pipet 2.0 mL of this
solution into a 100 mL volumetric flask and dilute to volume with acetonitrile.
The Standard Preparation contains about 0.005 mg per mL of each WIN compound.
Sample Preparation
------------------
Accurately weigh approximately 25 mg of sample into a 50 mL volumetric flask.
Dissolve in and dilute to volume with acetonitrile. Prepare immediately prior to
chromatographing.
System Suitability Tests
------------------------
The chromatographic system is considered suitable if it passes the following
test for Capacity Factor, Resolution and Precision.
. Capacity Factor and Resolution
------------------------------
Prepare a 1 mg/mL solution of sodium nitrate in water for use in determining the
colume void time t[a]. Inject 10 microliters of the sodium nitrate solution
onto the column and record the retention time of the peak due to sodium nitrate.
Inject the Standard Preparation, using the same volume and conditions described
above. Adjust the water/acetonitrile ratio of the mobile phase to achieve a
minimum k' value for WIN 61836 of 1.5 (increasing the water/acetonitrile ratio
will increase k'). The Resolution Factor for WIN 61836 and WIN 62058 must be
not less than 5. Additionally, the Resolution Factor for WIN 61834 and WIN
65489 must be not less than 7. Relative retention times have been found to be
1.0 for WIN 61836, about 1.7 for WIN 62058, 3.7 for WIN 61834 and 5.3 for WIN
65489.
Note: Resolution between WIN 61834 and WIN 65489 can be increased by decreasing
----
the amount of 85% phosphoric acid in the mobile phase to increase the retention
time of WIN 65489. This is most easily accomplished by adding small amounts of
51:49 acentonitrile-water. WIN 61836, WIN 62058 and WIN 61834 are weakly
affected by acid concentration and WIN 65489 is weakly affected by mobile phase
strength.
CONT'D EXHIBIT C
Intermediates - IND
-------------------
63843-AS-204.00 -4 of 6-
Calculate the capacity factor (k') and resolution (R) by the method of
calculation described in the current USP under <621> Chromatography.
Precision
---------
Make at least three replicate injections of Standard Preparation using the same
volume and conditions as in the Resolution test. The calculated relative
standard deviations of the peak responses for each compound in the last three
injections must be not more than 4%.
Procedure
---------
Using the bracketing standard technique, inject the Standard Preparation and the
Sample Preparation(s) onto the column, using the same volume and conditions used
for the System Suitability tests. Measure the peak responses obtained for each
of four WIN compounds in the two Standard Preparations bracketing the Sample
Preparation. Average the two responses for each WIN compound and record each as
R//s win //#. Measure the peak responses of the components from the Sample
Preparation at the same retention times as those obtained for WIN 61836, WIN
62058 and WIN 61834 in the Standard Preparation, recording them as R//u win# //.
Calculate the concentration of WIN 61836, WIN 62058 and WIN 61834 (in % w/w) in
the sample using the following formula:
(R//u win# // / R//s win#//) x C//win # // x 5000
-------------------------------------------------
W
where C//win # // is the concentration, in mg/mL, of each WIN compound in the
Standard Preparation and W is the sample weight in mg.
Measure the peak areas of unknowns in the Sample Preparation, recording them as
A//u//. Estimate the concentration of unknowns (in % w/w) in the sample using
the following formula:
CONT'D EXHIBIT C
Intermediates - IND
-------------------
63843-AS-204.00 -5 of 6-
(A//u// / A//s //) x C x 5000
-----------------------------
W
where A//s // is the area of the peak due to WIN 65489 in the Standard
Preparation, C is the concentration, in mg/mL, of WIN 65489 in the Standard
Preparation and W is the sample weight, in mg. Calculations may be performed
using either peak height or peak area measurements except for the determination
of unknowns, which uses peak area measurements only.
. Reporting
---------
Report individual values for WIN 61836, WIN 62058 and WIN 61834 to the nearest
0.1% w/w. For values less than 0.1%, report as: Trace, less than 0.1% w/w.
For unknowns, report total number of unknowns observed and a single value to the
nearest 0.1% w/w for unknown impurities. For values less than 0.1% w/w, report
as; Trace, less than 0.1% w/w.
