Participants

Reaction Steps

To a stirred solution of (2S,5R)-1-(chloroacetyl)-5-ethynylpyrrolidine-2-carbonitrile (0.05 g, 0.25 mmol, Example 8D) in acetonitrile (3 mL ) at room temperature under nitrogen, was added 6-(2-amino-2-methyl-propoxy)-nicotinonitrile (0.1 g, 0.508 mmol). The reaction mixture was stirred overnight and then concentrated under reduced pressure. The residue was flash chromatographed with 2% MeOH/CH2Cl2 to provide the desired compound as a white solid. MS (DCI) m/z 352 (M+H)+; 1H NMR (300 MHz, DMSO-d6) δ 2.01-2.04 (2H, m), 2.05 (2H, s), 2.07 (2H, s), 3.03 (1H, m), 3.04 (6H, s), 3.5-4.57 (2H, m), 4.57-4.58 (1H, m), 4.58-5.59 (1H, m), 7.0-7.08 (3H, m).
