Participants

Reaction Steps

197 mg of ethyl 5-chloro-1,6-dimethyl-4-hydroxy-2-oxo-1,2-dihydropyridine-3-carboxylate and 76 mg of 2-amino-1,3,4-thiadiazole were added to 2 ml of bromobenzene, then, the mixture was stirred for 5 hours under heat refluxing condition. The reaction mixture was cooled to room temperature, then, to the reaction mixture was added n-hexane. The resulting solid was collected by filtration, and washed with a mixture of t-butyl methyl ether and n-hexane and dried to obtain 183 mg of N-(1,3,4-thiadiazol-2-yl)-5-chloro-1,6-dimethyl-4-hydroxy-2-oxo-1,2-dihydropyridine-3-carboxamide (hereinafter, referred to as present compound 14) represented by the formula:
