실험 절차

To a solution of (S)-1-benzyl-2-(2,2,2-trifluoroethoxymethyl)-pyrrolidine (0.5 g, 1.83 mmol) in MeOH (20 mL) was added Hunig's base (1.18 g, 9.15 mmol). The flask was purged three times with Ar and 10% Pd/C (0.487 g, 0.457 mmol) was added to the mixture. The flask was purged three times with hydrogen and the reaction mixture was stirred at room temperature for 1 h. The mixture was filtered through a pad of Celite, washed with MeOH (20 mL) and the resulting solution was concentrated in vacuo to give the title compound (0.250 g, 75%) as a colorless semi-solid. MS: 184.1 (M+H+).
