4-Phenylbutyric Acid → N-(4-nitrophenyl)isoindoline-2-carboxamide

Participants

Reaction Steps

A solution of N-(4-aminophenyl)isoindoline-2-carboxamide (100 mg, 0.395 mmol), 4-phenylbutanoic acid (78 mg, 0.474 mmol), 1-hydroxybenzotriazole hydrate (66.5 mg, 0.434 mmol) and N-methylmorpholine (0.109 ml, 0.987 mmol) in N,N-dimethylformamide (1.771 ml) at room temperature was treated with N-(3-dimethylaminopropyl)-N′-ethylcarbodiimide hydrochloride (136 mg, 0.711 mmol). The mixture was stirred overnight and diluted with water (10 ml); the resulting suspension was filtered with water washes to give after drying product with an impurity. This solid was suspended in 2% methanol/dichloromethane and filtered to provide the title compound.
