Reaction Steps
In 3 ml of N,N-dimethylformamide, 350 mg of 3-methylsulfonyl-5-(3-fluorophenyl)-1,2,4-thiadiazole and 105 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 10 minutes, and further stirred at room temperature for 4 hours. 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 289 mg of 5-(3-fluorophenyl)-3-(2-butynyloxy)-1,2,4-thiadiazole (the compound (6) of the present invention).
