실험 절차

A mixture of 12 parts of ethyl carbonochloridate, 31 parts of (2-methylphenyl)[1-(phenylmethyl)-4-piperidinyl]methanone and 270 parts of dimethylbenzene is stirred and refluxed for 4 hours. The reaction mixture is evaporated and the residue is dissolved in trichloromethane. The solution is washed with a dilute hydrochloric acid solution. The organic phase is separated, dried, filtered and evaporated, yielding 20 parts of ethyl 4-(2-methylbenzoyl)-1-piperidinecarboxylate as an oily residue.
