p-Toluidine → 1-(4-Methylphenyl)aminocyclobutanenitrile

Participants

Reaction Steps

Trimethylsilyl cyanide (0.93 ml, 7 mmol) was added dropwise to a mixture of p-toluidine (0.535 g, 5 mmol) and cyclobutanone (0.42 g, 6 mmol). The reaction mixture was stirred at room temperature for 6 h and then concentrated under vacuum to obtain a brown liquid which was subjected to chromatography (dichloromethane) to yield 1-(4-methylphenyl)aminocyclobutanenitrile, 7a (0.912 g, 4.9 mmol, 98%) as a yellowish solid.
