Procedure

A mixture of 3,3-dimethyl-pentane-1,5-diol (1.5 g, 11 mmol) and imidazole (1.4 g, 20 mmol) in dichloromethane (50 mL) was added tert-butyldimethylchlorosilane (1.7 g, 11 mmol). The reaction mixture was stirred at room temperature for 2 h. Water was added. The organic layer was separated, the aqueous layer was then extracted with dichloromethane. The combined organic layers were washed with brine, dried over MgSO4, concentrated to give 5-(tert-butyl-dimethyl-silanyloxy)-3,3-dimethyl-pentan-1-ol as a colorless oil (2.7 g, 100%).
