Reaction Steps

In 3 ml of N,N-dimethylformamide, 400 mg of a mixture of 3-methylsulfonyl-5-(2-chlorophenyl)-1,2,4-thiadiazole and 3-methylsulfinyl-5-(2-chlorophenyl)-1,2,4-thiadiazole and 114 mg of 2-butyne-1-ol were dissolved, to the resulting solution was added 65 mg of sodium hydride (60% oily) with ice-cooling, and the mixture was stirred for 1 hour, and further stirred at room temperature for 1 hour. Then, the reaction mixture was poured into an aqueous saturated sodium chloride solution, and the mixture was extracted with t-butyl methyl ether. The residue obtained by concentration of the organic layer was subjected to silica gel column chromatography to obtain 210 mg of 5-(2-chlorophenyl)-3-(2-butynyloxy)-1,2,4-thiadiazole (the compound (8) of the present invention).
