Procedure

257 mg of ethyl 1,6-dimethyl-4-hydroxy-2-oxo-1,2-dihydropyridine-3-carboxylate and 260 mg of 2-aminoimidazole were added to 5 ml of bromobenzene, then, the mixture was stirred for 2 hours under heat refluxing condition. Further, to the mixture was added 151 mg of ethyl 1,6-dimethyl-4-hydroxy-2-oxo-1,2-dihydropyridine-3-carboxylate, and the resultant mixture was stirred for 2.5 hours under heat refluxing condition. The reaction mixture was cooled to room temperature. The resulting solid was collected by filtration, and washed with a mixed solvent of t-butyl methyl ether and hexane and dried to obtain 580 mg of 1,6-dimethyl-4-hydroxy-N-(2-imidazolyl)-2-oxo-1,2-dihydropyridine-3-carboxamide (hereinafter, referred to as present compound 26) represented by the formula:
