Participants

Reaction Steps

A solution of 2,2,2-trifluoroacetophenone (7.0 g, 40 mmol), R-(+)-α-methylbenzylamine (7.75 mL, 60 mmol), and p-toluenesulfonic acid monohydrate (0.77g, 4.0 mmol) in toluene (40 mL) was refluxed for 18 hours with a Dean-Stark trap. After cooling, the reaction mixture was diluted with toluene (50 mL), washed with 5% NaOH (1×50 mL), saturated NH4Cl (4×30 mL) and brine, dried over MgSO4, concentrated and dried at room temperature in vacuum to give the title compound as pale yellow liquid (11.1 g).
