Reaction Steps

A mixture of methanol (390 mL), water (80 mL), 7-(1-oxo-3-amino-4-(2,4,5-trifluorophenyl)-butyl)-3-trifluoromethyl-5,6,7,8-tetrahydro-1,2,4-triazolo[4,3-a]pyrazine (13 g), and di-p-tolyl-L-tartaric acid (13 g) is stirred for about 24 hours. The separated solid is filtered off, washed with ethanol (15 mL) and dried at about 45° C. to afford the title compound. (Yield: 66.3%; purity by HPLC: 99.93%)
