At room temperature, cyclopentylamine (5.794 mL, 58.7 mmol) was added dropwise to a solution of acrylonitrile (5.79 mL, 88.1 mmol) in methanol (7 mL). The solution was stirred at room temperature for 30 mins and at reflux for 1 hr, cooled to room temperature, and concentrated under reduced pressure. The desired product as obtained by distillation under vacuum to provide a clear liquid (7.4 g, 91%). 1H NMR (CDCl3, 300 MHz) δ 3.14-3.04 (quint, 1H, J=6.3 Hz), 2.91-2.87 (t, 2H, J=6.9 Hz), 2.53-2.48 (td, 2H, J=0.9, 6.9 Hz), 1.88-1.78 (m, 2H), 1.73-1.49 (m, 4H), 1.36-1.24 (m, 2H), 1.19 (br s, 1H).
