Participants

Reaction Steps

To a solution of (S)-1-((R)-2-amino-2-phenylacetyl)-N-(3-(4-(2-((S)-1-((R)-2-amino-2-phenylacetyl)pyrrolidin-2-yl)-1H-imidazol-4-yl)phenyl)cyclobutyl)pyrrolidine-2-carboxamide (80 mg, 0.124 mmol) in dichloromethane (20 mL), cyclopropyl carboxylic acid (22 mg, 0.26 mmol), DIPEA (0.5 mL) and HATU (94 mg, 0.26 mmol) were added at rt. After stirring overnight, the reaction was washed with brine and H2O, dried with Na2SO4. After removal of the solvent, the crude product was purified by silica gel column chromatography (DCM/MeOH=10/1 (v/v)) to afford (S)-1-((R)-2-(cyclopropanecarboxamido)-2-phenylacetyl)-N-(3-(4-(2-((S)-1-((R)-2-(cyclopropanecarboxamido)-2-phenylacetyl)pyrrolidin-2-yl)-1H-imidazol-4-yl)phenyl)cyclobutyl)pyrrolidine-2-carboxamide (A14) (25 mg).
