Procedure

1-{2-[3-(3,4,5-Trichlorophenyl)-3-(trifluoromethyl)pyrrolidin-1-yl]-4-(trifluoro-methyl)-1,3-thiazol-5-yl}methanamine (0.1 g) and triethylamine (0.05 g) were added to dichloromethane (20 mL), followed by the dropwise addition of dichloromethane solution (10 mL) comprising anhydrous propionic acid (0.05 g) under ice cooling. After the dropwise addition was completed, the reaction solution was stirred at room temperature for one hour. The solvent was evaporated off under reduced pressure, and the residue was then purified by a silica gel chromatography to obtain the title compound (0.1 g, 90%).
