실험 절차
To a solution of 5-hexyn-1-ol (9.81 g) in dichloromethane (50 ml) was added, at 0° C., triethylamine (10 ml), t-butyldimethylsilylchloride (17 g) and 4-dimethylaminopyridine (100 mg) and the mixture was stirred 16 hrs. while warming to room temperature. Dichloromethane (100 ml) was added and the organic layer was washed with 1N HCl (2×50 ml), brine and dried with Na2SO4. Solvents were removed and residue distilled under vacuum to yield the title compound as an oil (19 g, 89%).
