반응 단계
A solution of 1,4-butanediol (10.54 g, 0.117 mol) in dry THF (100 mL) was treated with t-butyl dimethylsilylchloride (17.30 g, 0.114 mol) and imidazole (7.80 g, 0.114 mol). After 2 h at room temperature, work-up with ethyl acetate and water, followed by drying the organic phase and concentration, gave a crude product that was purified by silica gel flash chromatography (being eluted with 20% ethyl acetate in hexane) to yield 15.5 g (Y: 65%) of 4-(t-butyldimethylsilyloxy)-1-butanol (XXVIIa) as a colorless oil; 1H-NMR (CDCl3, 300 MHz) δ ppm: 3.58 (m, 4H) 1.58 (m, 4H) 0.84 (s, 9H) 0.01 (s, 6H).
