Versuchsvorschrift

In 3 ml of tetrahydrofuran were dissolved 398 mg of 3-methylsulfonyl-5-(thiomorpholino)-1,2,4-thiadiazole and 180 mg of 2-butyn-1-ol, and 102 mg of sodium hydride (oil suspension; content: 60 weight %) was added at room temperature. The mixture was stirred at room temperature for 1 hour. The reaction mixture was concentrated. The residue was subjected to recrystallization from a mixed solvent of hexane-ethyl acetate to obtain 246 mg of 3-(2-butynyloxy)-5-thiomorpholino-1,2,4-thiadiazole (hereinafter, referred to as the present compound (23)).
