Sodium Chloride → 5-(6-Chloro-2-pyridylmethyloxy)-3-methylthio-1,2,4-thiadiazole

Participants

Reaction Steps

Into 3 g of N,N-dimethylformamide were dissolved 251 mg of 5-chloro-3-methylthio-1,2,4-thiadiazole and 188 mg of 6-chloro-2-pyridylmethyl alcohol, 72 mg of sodium hydride (60% in oil) was added thereto at room temperature, and the reaction mixture was stirred for 30 minutes. The reaction mixture was added to saturated sodium chloride aqueous solution, and extracted with t-butyl methyl ether. The organic layer was concentrated, and the residue obtained was subjected to silica gel column chromatography to give 44 mg of 5-(6-chloro-2-pyridylmethyloxy)-3-methylthio-1,2,4-thiadiazole (hereinafter, referred to as the present compound (35)).
