Procedure

(2S,5S)-1-(2-Chloro-acetyl)-5-methyl-pyrrolidine-2-carbonitrile (50 mg, 0.30 mmol) and cyclopentylamine (0.059 mL, 0.6 mmol) were dissolved in acetonitrile (2 mL) and stirred overnight. The product was purified by reverse phase HPLC eluting with 0% to 70% acetonitrile/0.1% aqueous trifluoroacetic acid. 1H NMR (300 MHz, methanol-d4) δ ppm 1.36 (d, J=6.44 Hz, 3H), 1.68 (m, 5H), 1.85 (m, 3H), 2.16 (m, 3H), 2.38 (m, 3H), 3.60 (m, 1H), 4.20 (m, 1H), 4.77 (m, 1H). MS (ESI) m/z 236 (M+H)+.
