p-Toluidine → 1-p-Tolylaminocyclohexanecarbonitrile

Participants

Reaction Steps

Sodium cyanide (0.147 g, 3 mmol) was added to a mixture of p-toluidine (0.214 g, 2 mmol) and cycloheptanone (0.337 g, 3 mmol) in acetic acid 90% (3 ml). The reaction mixture was stirred at room temperature for 12 h and then 20 ml of ethyl acetate was added. The organic layer was washed with water (3×10 ml), dried over magnesium sulfate and concentrated under vacuum to dryness to yield 1-(4-methylphenyl)aminocyclohexanenitrile, 10a (0.438 g, 1.92 mmol, 96%) as a brown solid.
