Procedure

213 mg of ethyl 1,6-dimethyl-4-hydroxy-2-oxo-1,2-dihydropyridine-3-carboxylate and 79 mg of 3-amino-5-methylisooxazole were added to 2.5 ml of bromobenzene, then, the mixture was stirred for 6.5 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 141 mg of 1,6-dimethyl-4-hydroxy-N-(5-methylisooxazol-3-yl)-2-oxo-1,2-dihydropyridine-3-carboxamide (hereinafter, referred to as present compound 27) represented by the formula:
