反应详情

To a mixture of 28 ml of 30% sdium methanolate solution and 50 ml of methanol are added 14.1 g (0.15 mole) of phenol. The reaction mixture is evaporated in a vacuum and the residue is taken up in 120 ml of N,N-dimethyl formamide, 35.5 g (0.15 mole) of N-benzoyl-4chloromethylpiperidine are added thereto and the reaction mixture is stirred for 12 hours at 60°-70° C. After cooling, the reaction mixture is mixed with diethyl ether, washed with water and dilute aqueous sodium hydroxide solution, dried over anhydrous sodium sulfate and evaporated in a vacuum. The oily residue is triturated with diethyl ether/ligroin. There are obtained 23.0 g of N-benzoyl-4-phenoxymethylpiperidine (52% of theory); m.p. 95°-96° C.
