Versuchsvorschrift

t-Butyl dimethylsilylchloride (4.28 g, 28.4 mmol) and imidazole (4.83 g, 70.9 mmol) were added to a flask purged with N2 and dichloromethane (50 mL) was added. 3-Butene-1,2-diol (2.50 g, 28.4 mmol) was then added to the flask and the mixture was stirred for 2 hours. The solvent was removed and the titled product (2.71 g, 47.9%) was purified by column chromatography (5% ethyl acetate in hexanes).
