Reaction Conditions

Reaction Steps

Water (1 mL) was added to a solution of 3-(1-benzenesulfonyl-3-cyano-1H-indole-5-carbonyl)-3-benzyl-pyrrolidine-1-carboxylic acid tert-butyl ester (100 mg, 0.175 mmol) in MeOH (4 mL), followed by potassium carbonate (73 mg, 0.525 mmol). The reaction mixture was heated at 50° C. for 10 minutes, then cooled to room temperature and diluted with water and brine. The resulting mixture was extracted with DCM, dried over MgSO4, filtered and evaporated under reduced pressure. The residue was purified by flash chromatography (30% to 50% of EtOAc in hexane) to give 3-benzyl-3-(3-cyano-1H-indole-5-carbonyl)-pyrrolidine-1-carboxylic acid tert-butyl ester as white foamy solid.
