Fractions of 25 ml 5 were collected. Al&tots of each fraction were assayed by thin-layer chromatography (TLC). Fractions containing the desiredproduct were pooled and evaporated to dryness. The product, diaaomethylketone, was purified as a pale yellow foam (6.54 g). 10 NCBOC-NJ?-Tos-&Homoargininc Methylester We dissolved the diazomcthylketone prepared above k! 100 mI of anhydrous methanol and refluxed that solution under argon while a solution of silver benxoate IS catalyst (165 tug in 400 p1 triethyhmine) wai added dropwise.

How is the "other individual impurity' reported; In the report from the Foundation of Neurologic Diseases in Attachment 2 of June 22 amendment #023, how was the "other individual impurity obtained; Request Dr. Wolfe at the Foundation for Neurologic Diseases to reanalyze the data to include the "Major Impurities Peak" at the RRT 1.04 and "Total Other Impurities". The latter calculation would be for the sum of all non-bivalirudin peaks besides the g-ASP analog and the "Major Impurity Peak" at RRT Response to FDA request for CMC Information: Dr. Wolfe's reanalvsis of the "Major Impurities Peak" at the RRT 1.04 and Tom Lateaan "Total Other Impurities".
