Procedure
To a stirred solution of 8 parts of ethyl 4-[(2,6-dimethylphenyl)amino]-1-piperidinecarboxylate in 4 parts of pyridine and 80 parts of benzene are added dropwise 7.7 parts of benzeneacetyl chloride in 40 parts of benzene. After the addition is complete, the whole is heated to reflux and stirred at reflux temperature for 3 h. 45. The reaction mixture is cooled and filtered. The benzene-phase is washed with water and then with sodium hydrogen carbonate solution and with water. After evaporation, an oily residue is obtained, which solidifies on triturating in 1,1'-oxybisethane, to yield 5 parts of ethyl 4-[N-(2,6-dimethylphenyl)-N-(phenylacetyl)amino]-1-piperidinecarboxylate; mp. 106° C.
