Dimethylformamide → n-(2-Aminophenyl)-6-(2-(2-(((6-trifluoromethyl-2-oxoindolin-3-ylidene)-hydrazono)methyl)-3,5-dimethyl-1h-pyrrole-4-carboxamido)ethylamino)nicotinamide

Participants

Reaction Steps

2-(((6-Trifluoromethyl-2-oxoindolin-3-ylidene)hydrazono)methyl)-2,4-dimethyl-1H-pyrrole-4-carboxylic acid (378 mg, 1 mmol) and 8 ml of DMF were stirred at room temperature while 1-Ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (384 mg, 2 mmol), hydroxybenzotriazole (162 mg, 1.2 mmol), triethylamine (404 mg, 4 mmol) and N-(2-aminophenyl)-6-(2-aminoethylamino)nicotinamide (284 mg, 1.05 mmol) were added. The mixture was stirred for 20 hours at room temperature. The mixture was diluted with 400 mL of brine. The solids were collected by vacuum filtration, washed with water and dried under vacuum to give the title compound (341 mg, 54%) as a red solid. LC-MS (m/z) 632 (M+1).
