Reaction Steps

In 2.5 ml of N,N-dimethylformamide, 350 mg of 3-methylsulfonyl-5-(3-chlorophenyl)-1,2,4-thiadiazole and 117 mg of 2-pentyne-1-ol were dissolved, to the resulting solution was added 56 mg of sodium hydride (60% oily) with ice-cooling, and the mixture was stirred for 30 minutes, 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 290 mg of 5-(3-chlorophenyl)-3-(2-pentynyloxy)-1,2,4-thiadiazole (the compound (78) of the present invention).
