Imidazole → HCID 58018637, compound

Participants

Reaction Steps

To a solution of ethyl 4-hydroxycyclohexane carboxylate (5 g, 29.03 mmol) in dichloromethane (200 mL) was added imidazole (4.97 g, 73 mmol) and tert-butylchlorodiphenylsilane (15.96 g, 15.2 mL, 58 mmol). The reaction mixture was allowed to stir at room temperature over night. The reaction mixture was poured into water (125 mL) in a separatory funnel and the phases were separated. The aqueous phase was extracted with dichloromethane (2×200 mL). The combined organic solutions were washed with brine, dried over Na2SO4, and concentrated under vacuum. Purification by column chromatography on silica gel eluting with ethyl acetate in heptanes (0-10%) afforded 10.55 g (89%) of the title compound.
