Procedure

To a stirred solution of (2S,5R)-1-(chloroacetyl)-5-ethynylpyrrolidine-2-carbonitrile (0.035 g, 0.178 mmol, Example 8D) in acetonitrile (3 mL) at room temperature under nitrogen was added cyclohexylamine (0.041 ml, 0.356 mmol), The reaction mixture was stirred at room temperature overnight and then concentrated under reduced pressure. The residue was flash chromatographed with 2-3% MeOH/CH2Cl2 to provide the desired compound as a pale yellow oil. MS (DCI) m/z 260 (M+H)+; 1H NMR (300 MHz, DMSO) δ 1.5-2 (10H, m), 2.13-2.31 (2H, m), 2.41-2.48 (2H, m), 3.76 (1H, d), 3.8-4.5 (2H, m), 4.53-4.55 (1H, t), 4.9 (1H, m), 5.05 (1H, m).
