实验步骤: To a solution of 3-pentyn-1-ol (750 mg, 9 mmol) and sodium hydride (310 mg, 9 mmol) in dry tetrahydrofuran was added a solution of 3-(4-chloro-1,2,5-thiadiazol-3-yl)pyridine (590 mg, 3 mmol) in dry tetrahydrofuran. The reaction mixture was stirred at room temperature for 1 h. Water was added and the mixture was extracted with ether. The ether phase was dried and evaporated to give the title compound. the mixture was extracted with ether The ether phase was dried evaporated

实验步骤: To a cold (0° C.) solution of 3-pentynol (5.880g, 70.0 mmol, 1.0 equiv), 4-dimethylaminopyridine (DMAP) (840 mg, 7.00 mmol, 0.10 equiv), and triethylamine (TEA) (9.80 ml, 71.0 mmol, 1.01 equiv) in 100 mL of dry hexane was added dropwise chlorodiisopropylsilane (11.0 g, 71.0 mmol, 1.01 equiv) over 20 minutes. The resulting white suspension was allowed to warm to room temperature and was stirred overnight. The reaction mixture was filtered through a short silica pad (10 g) and the solvent was then evaporated in vacuo to give a colorless liquid. Fractional distillation of this liquid afforded 11.2 g (81%) of A-7 as a colorless liquid. An analytical sample (0.48 g) was obtained by redistillation of a 0.50 g sample by Kugelrohr distillation. The reaction mixture was filtered through a short silica pad (10 g) the solvent was then evaporated in vacuo to give a colorless liquid Fractional distillation of this liquid afforded 11.2 g (81%) of A-7 as a colorless liquid An analytical sample (0.48 g) was obtained by redistillation of a 0.50 g sample by Kugelrohr distillation
