Procedure
211 mg of ethyl 1,6-dimethyl-4-hydroxy-2-oxo-1,2-dihydropyridine-3-carboxyl ate and 90 mg of 3-amino-5-methyl-1,2,4-triazole were added to 2.5 ml of bromobenzene, then, the mixture was stirred for 7 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 214 mg of 1,6-dimethyl-4-hydroxy-N-(5-methyl-1,2,4-triazol-3-yl)-2-ox o-1,2-dihydropyridine-3-carboxamide (hereinafter, referred to as present compound 24) represented by the formula:
