반응 단계

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.
