反应详情

A flask was charged with 10% palladium on carbon (200 mg), ethanol (20 mL), and 1-benzyloxy-2-(4-fluorophenyl)-4-ethyl-5-[(4-aminobutyl)oxy]-benzene (500 mg). The flask was fitted with a balloon and pressurized with hydrogen to fully inflate the balloon. The reaction was stirred 3.5 hours, filtered through Celite, and the filtrate concentrated under vacuum to afford 4-ethyl-2-(4-fluorophenyl)-5-[(4-aminobutyl)oxy]phenol as a white powder (350 mg). HPLC showed that ˜25% starting material remained. It was not purified but carried directly into the next step. Mass Spec (EI), m/e=304.1 (M+H).
