反応手順

A solution of trimethylsilyl propyn-1-ol (1 g, 7.8 mmol) and Et3N (1.4 mL, 10 mmol) in Et2O (10 mL) is cooled to −20° C. and a solution of methacryloyl chloride (0.9 mL, 9.3 mmol) in Et2O (5 mL) is added dropwise over 1 h. The mixture is stirred at this temperature for 30 min, and then allowed to warm to ambient temperature overnight. Any precipitated ammonium salts can be removed by filtration, and volatile components can be removed under reduced pressure. The crude product is then purified by flash chromatography.
