[1-(S)-Methyl-2-(4-trifluoromethoxy-phenylamino)-ethyl]-carbamic acid benzyl ester (23.9 mmol) was dissolved in ethanol (200 mL) then placed under nitrogen. 10% Palladium on carbon was added (0.5 g) and the mixture was stirred under hydrogen (atmospheric pressure) overnight. When reaction was complete, the mixture was filtered through celite. The celite was washed with ethanol (5×50 ml) then evaporated in vacuo to give a brown oil (4.03 g, 17.21 mmol, 72% yield over 3 steps).
