실험 절차

A mixture of 0.5 g of 2-(2-methoxyphenyl)oxirane (crude product) and 600 mg of 3,4-dimethoxyphenethylamine is heated at 130° to 140° C. for 2 hours. After cooling, chloroform is added to the reaction mixture, and said mixture is washed with water. The mixture is dried and evaporated to remove solvent. 2 ml of ethanol are added to the residue obtained. Then, hydrochloric acid-containing diethylether is added to the ethanol mixture, and crystalline precipitates are collected by filtration. 290 mg of α-(3,4-dimethoxyphenethylaminomethyl)-2-methoxybenzylalcohol hydrochloride are obtained as crystals. M.p. 142°-143° C.
