Procedure

5-Amino-5-benzyl-hexahydro-cyclopenta[c]pyrrole-2-carboxylic acid dimethylamide 14f (0.1 g, 0.35 mmol) was dissolved in 4 mL of the solvent mixture of dichloromethane/N,N-dimethylformamide (V/V=1/1) followed by addition of (2S,4S)-1-(2-chloroacetyl)-4-fluoropyrrolidine-2-carbonitrile 13g (66.5 mg, 0.35 mmol) and potassium carbonate (49 mg, 0.35 mmol). The reaction mixture was reacted at 40° C. for 12 hours. The reaction was monitored by TLC until the disappearance of the starting materials. The mixture was concentrated, and the resulting residue was purified by silica gel column chromatography to obtain the title compound 5-benzyl-5-[2-((2S,4S)-2-cyano-4-fluoro-pyrrolidin-1-yl)-2-oxo-ethylamino]-hexahydro-cyclopenta[c]pyrrole-2-carboxylic acid dimethylamide 14g (87 mg, yield 56%) as a white solid.
