Versuchsvorschrift

Step C To the solution of 3-ethyl-3-hydroxymethyl-pentanenitrile (1.7 g, 12 mmol) and imidazole (1.2 g, 18 mmol) in dichloromethane (80 mL) was added tert-butyldimethylchlorosilane (2 g, 13 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 3-(tert-butyl-dimethyl-silanyloxymethyl)-3-ethyl-pentanenitrile as a colorless oil (2.28 g, 74%).
