Procedure

In 20 ml of ethanol, is dissolved 2.20 g (8.49 mmol) of trans-1-benzyl-3-hydroxymethyl-4-trifluoromethylpyrrolidine, and 1 ml of conc-hydrochloric acid is added to the solution. A hydrogenation is performed by adding 440 mg of 10% palladium carbon to the above solution at 40° C. and 1 atmospheric pressure. Four hours later, the catalyzer was removed by filtration, and the filtrate was concentrated under reduced pressure to give 1.74 g of the objective substance as a colorless powder (yield 99.7%).
