Reaction Steps

4-Chloro-1-butanol (5.43 g, 50 mmol) was dissolved in dimethylformamide (50 mL) and tert-butyldimethylsilylchloride (7.54 g, 50 mmol) was added, followed by imidazole (3.4 g, 50 mmol). After 24 hours of stirring at room temperature, the reaction mixture was diluted with hexane, washed with water and brine and dried over anhydrous sodium sulfate. The solvent was evaporated to give colorless liquid which was purified by chromatography on silica gel eluting with hexane/ethyl acetate (30:1) to give the product (7.26 g, 56%). 1H NMR (CDCl3) δ: 0.05 (s, 6H), 0.89 (s, 9 H), 1.64-1.68 (m, 2H), 1.82-1.86 (m, 2H), 3.57 (t, 2H), 3.64 (t, 2 H).
