실험 절차

To a stirred mixture of 35 parts of (3-methylphenyl) (1-methyl-4-piperidinyl)methanone, 1 part of sodium carbonate and 225 parts of dimethylbenzene are added dropwise 22 parts of ethyl carbonochloridate at 20° C. Upon completion, stirring is continued for 6 hours at reflux temperature. The reaction mixture is evaporated, yielding 12 parts of ethyl 4-(3-methylbenzoyl)-1-piperidinecarboxylate as an oily residue.
