실험 절차

9.75 g (50 mmol) of 5-amino-2-chlorobenzotrifluoride and 7.15 g (50 mmol) of 2-isocyanato-2-methylpropionic acid methyl ester were admixed and melted at 80° C. The melt was maintained at 80° C. for 30 minutes. The resulting product which was crystallized during the process, was recrystallized from isopropanol/methylene chloride and dried at 50° C. for 20 hours, under greatly reduced pressure, to yield N-[(3-Trifluoromethyl-4-chloro-phenyl)-carbamoyl]-2-methylalanine methyl ester, m.p. 141°-142° C.
