4-Nitrophthalimide → 4-Aminophthalimide

Participants

Reaction Steps

To a solution of 5-nitro-1H-isoindole-1,3(2H)-dione (1.0 g, 5.2 mmol) in dry THF (15 mL) was added 10% Pd/C (0.2 g). The mixture was hydrogenated at 30-40 psi for 17 h. The catalyst was filtered, and the filtrate was evaporated under vacuo to give 0.5 g (59.3%) of 5-amino-1H-isoindole-1,3(2H)-dione as a yellow colour solid.
