Procedure
A mixture of 34 parts of ethyl 4-oxo-1-piperidinecarboxylate, 20 parts of 2-pyrimidinamine, 8 drops of acetic acid and 90 parts of methylbenzene is stirred and refluxed for 28 hours with water-separator. The reaction mixture is evaporated, yielding 50 parts of ethyl 4-(2-pyrimidinylimino)-1-piperidinecarboxylate as a residue.
