Sodium Chloride → 5-(5-Pyrimidylmethyloxy)-3-methylthio-1,2,4-thiadiazole

Participants

Reaction Steps

Into 4 g of N,N-dimethylformamide were dissolved 304 mg of 5-chloro-3-methylthio-1,2,4-thiadiazole and 200 mg of 5-pyrimidylmethyl alcohol, 97 mg of sodium hydride (60% in oil) was added thereto under ice-cooling, and the reaction mixture was stirred for 30 minutes. After stirring for 5 hours at room temperature, 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 210 mg of 5-(5-pyrimidylmethyloxy)-3-methylthio-1,2,4-thiadiazole (hereinafter, referred to as the present compound (37)).
