Reaction Conditions

Reaction Steps

A solution of N-(Diphenylmethylene)glycine ethyl ester (1.10 g, 4.1 mmol) and 3,4,5-trifluorobenzylbromide (0.91 g, 4.0 mmol) in dimethylformamide (10 mL) was treated with anhydrous potassium carbonate (2.83 g, 20.5 mmol) and stirred for 18 hrs at 25° C. The mixture was filtered and the filtrate was evaporated to dryness to give crude product. It was purified by column chromatography on silica gel (hexane:ethyl acetate=4:1) to give title compound (1.2 g).
