Ammonia → 4-Nitro-2,3-dihydro-1H-isoindol-1-one

Participants

Reaction Steps

To a solution of methyl-2-bromomethyl-3-nitro-benzoate (6.9 gm, 0.025 mol.) in methanol, was added slowly a methanolic solution of ammonia (50 ml), and the reaction mixture was stirred at room temperature for 2 hr. The pale yellow colored solid separated out was filtered, dried under vacuum to give 4-nitro-2,3-dihydro-1H-isoindol-l-one (compound 3, 3.570 gm, 81%).
