Potassium tert-butoxide → HCID 178509547, compound

Participants

Reaction Steps

A solution of potassium tert-butoxide (1.10 g) in tetrahydrofuran (50 mL) is added dropwise to a solution of 4-[1-(1,2,4-triazolyl)-5-chloropentyl]benzonitrile (2.50 g) in tetrahydrofuran at 0° (ice-bath). The reaction is allowed to proceed at 0° for 30 minutes and is then allowed to warm to room temperature during 3 hours. The reaction is then quenched with water (100 mL) and the mixture is subsequently extracted with ethyl acetate (100 mL). The organic extract is extracted with 3N hydrochloric acid (3×30 mL) and the combined acid extracts are made basic with 6N sodium hydroxide. The crude product is extracted into ethyl acetate (3×30 mL) and the combined extracts are dried (MgSO4) and evaporated to afford 1-(4-cyanophenyl)-1-(1,2,4-triazolyl)cyclopentane. The compound is dissolved in acetone and treated with ethereal HCl to afford the hydrochloride salt.
