실험 절차

213 mg of ethyl 1,6-dimethyl-4-hydroxy-2-oxo-1,2-dihydropyridine-3-carboxyl ate and 120 mg of 5-amino-3-ethyl-1,2,4-thiadiazole were added to 2.5 ml of bromobenzene, then, the mixture was stirred for 4 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 231 mg of 1,6-dimethyl-N-(3-ethyl-1,2,4-thiadiazol-5-yl)-4-hydroxy-2-oxo-1,2-dihydropyridine-3-carboxamide (hereinafter, referred to as present compound 19) represented by the formula:
