실험 절차

A mixture of 171 parts of ethyl 4-oxo-1-piperidinecarboxylate, 162 parts of 2,6-dichlorobenzenamine, 800 parts of dimethylbenzene and 1 part of 4-methylbenzenesulfonic acid is stirred and refluxed with water-separator. The reaction mixture is evaporated, yielding 250 parts of ethyl 4-[(2,6-dichlorophenyl)imino]-1-piperidinecarboxylate as a residue.
