Procedure
To a stirred solution of (2S,5R)-1-(chloroacetyl)-5-propynylpyrrolidine-2-carbonitrile (0.018 g, 0.086 mmol) in acetonitrile (1 mL) at room temperature was added cyclopentyl amine (0.017 mL, 0.17 mmol). The reaction mixture was stirred at room temperature for 18 hours, concentrated under reduced pressure and purified by flash chromatography with 3% methanol/97% dichloromethane to provide the titled compound.
