Sodium cyanide (23.7 g, 482 mmol) was added to a solution of ammonium hydroxide (28%, 122 mL, 965 mmol) and ammonium chloride (28.4 mL, 531 mmol) in water (100 mL). Cyclohexanone (50 mL, 482 mmol) was added over 5 min. The reaction was heated at 60° C. for 6 h, then was allowed to cool to rt and stir overnight. The mixture was transferred to a separatory funnel and was washed with dichloromethane (3×200 mL). The organic layers were combined, dried over MgSO4, filtered, and concentrated under reduced pressure. Purification by flash chromatography (silica gel, eluted with 20% hexanes/ethyl acetate) provided 1-aminocyclohexanecarbonitrile as a clear oil (49.5 g, 83%).
