실험 절차

The process according to Example 6 is carried out except that p-chloro-aniline is replaced by aniline and ethyl-6-methyl-4-oxo-6,7,8,9-tetrahydro-4H-pyrido(1,2-a)pyrimidine-3-carboxylate is replaced by ethyl-7-methyl-4-oxo-6,7,8,9-tetrahydro-4H-pyrido(1,2-a)pyrimidine-3-carboxylate, respectively. Thus ethyl-9-(phenyl-hydrazono)-7-methyl-4-oxo-6,7,8,9-tetrahydro-4H-pyrido(1,2-a)pyrimidine-3-carboxylate is obtained with a yield of 60.2%. Mp.: 165°-167° C.
