Reaction Steps

To a solution of 3-(4-methyl-5-((2-oxoindolin-3-ylidene)methyl)furan-2-yl)benzoic acid (40 mg, 0.12 mol) and HOBt (32 mg, 0.24 mol) in DMF (0.5 mL) was added EDCI (46 mg, 0.24 mmol). The reaction was stirred at rt for 10 min and then added 2-(pyrrolidin-1-yl)ethanamine (0.05 mL) followed by DIEA (0.05 mL). The reaction mixture was stirred at rt for 1 h and diluted with H2O (10 mL). The mixture was extracted with EtOAc (3×20 mL), dried over Na2SO4 and concentrated. The crude was purified by prep TLC (5%/MeOH, 1% TEA/DCM) to give 3-(4-methyl-5-((2-oxoindolin-3-ylidene)methyl)furan-2-yl)-N-(2-(pyrrolidin-1-yl)ethyl)benzamide (25 mg) LCMS (ES): m/z 442 [M+1]+.
