실험 절차

To a mixture of 28 ml of 30% sodium methanolate solution and 50 ml methanol, there are added 14.1 g (0.15 mole) of phenol. The reaction mixture is evaporated, mixed with 50 ml of N,N-dimethyl formamide and 7.8 g (0.05 mole) of 4-chloromethylpiperidine hydrochloride and heated for 18 hours at 70°-80° 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. There are obtained 3.1 g of 4-phenoxymethylpiperidine (32% of theory); m.p. 41°-42° C.
