Procedure
At room temperature, cyclobutylamine (5.90 mL, 59.8 mmol) was added dropwise, over 15 mins, to a solution of acrylonitrile (4.76 g, 89.7 mmol) in methanol (7 mL). The mixture was stirred at room temperature for 30 mins and at reflux for 1 hr, cooled to room temperature, concentrated under reduced pressure. The desired product was obtained by distillation under vacuum to provide a clear liquid (7.7 g, 98%). 1H NMR (CDCl3, 300 MHz) δ 3.29-3.21 (m, 1H), 2.88-2.83 (t, 2H, J=6.6 Hz), 2.50-2.46 (t, 2H, J=6.6 Hz), 2.26-2.20 (m, 2H), 1.76-1.63 (m, 4H), 1.30 (br s, 1H).
