The vial was sealed with a cap containing a PTFE septum and removed from the dry box. Methacrylonitrile (270 mg, 4.00 mmol) and aniline (93.1 mg, 1.00 mmol) were added to the reaction mixture by syringe. The reaction mixture was stirred at room temperature for 24 h, after which time it was adsorbed onto silica gel. The product was isolated by eluting with 15% ethyl acetate/hexanes to give 142 mg (89%) of 2-anilino-1-methylethyl cyanide. 1H NMR: (CDCl3) δ 7.22 (t, J=7.6 Hz, 2H), 6.78 (t, J=7.6 Hz, 1H), 6.63 (d, J=7.6 Hz, 2H), 3.71 (brs, 1H) 3.43 (dd, J=13.8, 8.0 Hz, 1H), 3.37 (dd, J=13.8, 6.0 Hz, 1H), 2.99 (m, 1H), 1.38 (d, J=7.1 Hz, 3H). 13C{1H} NMR: (CDCl3) δ 146.52, 129.50, 121.81, 118.50, 113.04, 47.04, 25.98, 15.39.
