Reaction Steps

4-(t-Butyldiphenylsiloxy)-pentanol (15 g, 0.04 mol) was dissolved in methylene chloride (100 mL) containing pyridine (7 g). Tosyl chloride (15.3 g, 0.08 mol) was added slowly and the mixture stirred overnight. The mixture was washed with saturated NaHCO3 (2×100 mL) and the aqueous then backwashed with methylene chloride (100 mL). The organic phases were combined and washed with 2M HCl (100 mL) and water. The solution was dried over Na2SO4, evaporated and purified by column chromatography (light petroleum: ethyl acetate, 3:1) to give the title compound as a thick oil (yield 85%). δC (CDCl3, 62.9 MHz): 19.2, 21.7, 21.8, 26.9, 28.6, 31.8, 63.5, 70.6, 127.7, 127.9, 129.6, 129.9, 133.2, 133.9, 135.6 and 144.7
