실험 절차

Triethylamine (4.3 ml) was added to a solution of 9-dodecyn-1-ol (5.1 g, 28 mmol) in 50 ml CH2Cl2, and the mixture was then added dropwise at 0° C. to a solution of methanesulfonyl chloride (2,2 ml, 28 mmol) in 10 ml CH2Cl2. The mixture was stirred another 4 hours at room temperature, then cooled to 0°-5° C. The solution was washed with cold 5% aqueous sodium bicarbonate, cold 1N HCl, cold water, then saturated brine. The extract was dried over Na2SO4 and filtered and evaporated. The solvent was evaporated to leave crude 1-(9-dodecynyl) methanesulfonate.
