Procedure
Sodium cyanide (0.147 g, 3 mmol) was added to a mixture of p-toluidine (0.214 g, 2 mmol) and cyclobutanone (0.21 g, 3 mmol) in 90% acetic acid (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)aminocyclobutanenitrile, 7a (0.343 g, 1.84 mmol, 92%) as a brown solid.
