Participants

Reaction Steps

To a suspension of tert-butyl 5-methyl-2-(2,2,2-trifluoroacetamido)benzoate (19.78 mmol, 6.0 g) in ethanol (19 ml) was cooled with a water-iced bath. NaBH4 (39.57 mmol, 1.50 g) was added in portions and the mixture was stirred at room temperature for 3 hours. Water (40 ml) was added slowly and evaporated. The solid was dissolved with CHCl3 and washed with water and brine. The organic phase was evaporated affording 3.73 g (yield 91%) of the expected product.
