It has been known that a compound belonging to the 4-oxo-3-pyridinecarboxamide derivative is produced by reacting a suitable 3-aminocrotonamide derivative with diketene in the absence of a solvent. In other words, Kato et al. (Pharmaceutical magazine, 10

-Chlorophenyl group; R 2 = phenyl group: R 3 = methyl group and corresponds to the case of n = 1) without using a solvent, and the reaction mixture obtained by reacting diketene under heating at 60 to 90 ° C. From 1,4-dihydro-2,6-dimethyl-4-, which can be isolated by silica gel column chromatography.
Oxo-N-phenyl-1-phenylmethyl-3-pyridinecarboxamide and its derivative (in the formula (III), R 1 = phenyl group, 4-methoxyphenyl group and 4-chlorophenyl group; R 2 = phenyl group; R 3 = Methyl groups and corresponding respectively when n = 1) in yields of 2 to 9%. This method uses diketene that is industrially easily available and has a simple operation in which the reaction is simply performed under heating. However, in all cases reported, the yield is low and the method is industrially applied. It cannot be considered as a possible manufacturing method. The main product of the reaction by the method of Kato et al. Is rather 4-hydroxy-6-methyl-1-phenyl-3- [1- (phenylmethylimino) ethyl] -2 (1H) -pyridinone or its derivative.

2,6-dimethyl-4-oxo-N- (4-chlorophenyl) -3-pyridinecarboxamide hydrochloride is obtained,
In addition, free carboxamide is obtained (see patent example 14 above). This method uses a solvent for the reaction, reacts diketene in the presence of triethylamine,
Although it is different from the method of Kato et al. Described above in that the reaction product is insolubilized as a hydrochloride, the yield of the product is not described, and its usefulness as a production method is unknown.
