실험 절차
To a solution of (1R,2S)—N-[(1R)-1-phenylethyl]-2-(trifluoromethyl)cyclohexanamine (3.53 g) and 13 mL of HCl (2M ethanol solution) in 35 mL of ethanol was added Pd(OH)2(2.78 g) under N2. H2 gas was purged and stirred for 2 days under 4 atm at 60° C. Pd(OH)2 was filtered off through a pad of Celite. Solvent was removed under reduced pressure. (1R,2S)-2-(Trifluoromethyl)cyclohexanamine hydrochloride (2.37 g) was obtained as a white solid.
