Procedure

Imidazole (6.77 g) was added to a solution containing 1,4-butanediol (58.8 mL) in DMF (60.0 mL) at room temperature. A solution of tert-butyldimethylsilyl chloride (10.0 g) in dichloromethane (5.0 mL) was added dropwise, and the mixture was stirred at the same temperature for three hours. Diethyl ether and water were added to the reaction solution. The organic layer was separated, washed with water and a saturated sodium chloride solution and then dried over anhydrous magnesium sulfate. The insoluble matter was separated by filtration and the filtrate was concentrated to obtain the title compound (13.4 g).
