실험 절차

In a bottle were placed 9 g of 10% palladium-carbon, 180 ml of methanol, 275 ml of ethanol, 6.5 ml of concentrated hydrochloric acid and 9 g of the hydrochloride salt of (2S,3S)-3-(2-methoxybenzylamino)-2-phenylpiperidine. The mixture was shaken under hydrogen (40 p.s.i.) overnight, after which 9 g of additional catalyst were added to the system and the mixture was shaken under hydrogen for 1 day. The mixture was diluted with water (250 mL), filtered through diatomaceous earth (Celite (trademark)) and the Celite was rinsed well with water. The filtrate was concentrated to a volume of ca. 600-700 mL, made basic with concentrated aqueous sodium hydroxide and extracted with chloroform. The chloroform extracts were dried (sodium sulfate) and concentrated to obtain 4.4 g of the title compound as a colorless oil.
