Reaction Steps

To a solution of 1,4-butanediol (5 g, 55 mol) in dichlormethane (10 mL) containing diisopropylethylamine (10 mL) was added tert-butylchlorodiphenylsilane (5 mL, 18 mmol) dropwise under N2 atmosphere at 18° C. over 2 h. The resultant solution was stirred at room temperature for 4 hours and concentrated under reduced pressure. Purification by column chromatography with hexane/ethyl acetate (1/1) gave 4-(tert-butyl-diphenyl-silanyloxy)-butan-1-ol (10.2 g, 85% yield) as colorless oil: 1H NMR (400 MHz, CDCl3) δ 7.62-7.71 (4H, m); 7.32-7.43 (6H, m), 3.63-3.69 (4H, m), 1.83 (1H, br s), 1.59-1.71 (4H, m), 1.03 (9H, s).
