Reaction Steps

To a stirred mixture of 2-trityloxymethyl-1,4-butandiol (50.85 g, 0.140 mol) and triethylamine (42.6, 0.42 mol) in dry diethyl ether (500 ml) was added slowly a solution of acetyl chloride (27.5 g, 0.35 mol) in ether (25 ml) with external cooling with cold water to maintain room temperature in the mixture. After 45 min the triethylamine hydrochloride was filtered off and washed with a little ether. The combined filtrate was washed with water (50 ml), 0.5M hydrochloric acid (100 mi) and water (50 ml), dried with magnesium sulfate and evaporated in vacuum, finally at 0.1 mBar, to give 61.03 g (97%) of crude oily product. TLC on silica (ethyl acetate+n-hexane 1+1): Rf 0.68.
