실험 절차

A mixture of 7.78 g (0.025 mole) of 4-[bis(4-methoxyphenyl)methyl]piperidine, 6.05 g (0.025 mole) of 1-[4-(3-chloropropoxy)-3-methoxyphenyl]ethanone, and potassium carbonate (5.53 g, 0.04 mole) in 300 ml of 1-butanol containing potassium iodide (0.3 g) was refluxed overnight. The reaction mixture was stripped to dryness and the residue was partitioned between chloroform and water; removal of chloroform in vacuo gave a dark brown oil. The oil was subjected to column chromatography on silica gel using a gradient elution composed of methanol and ethyl acetate. The corresponding fractions from the column were combined and reacted with oxalic acid. Recrystallization of the salt from methanol-diethyl ether gave 4.16 g (27.4%) of white solid, m.p. 163.5°-165° C.
