Procedure

To a solution of 2-(3-(3-nitropyridin-4-yl)cyclohex-2-enyl)isoindoline-1,3-dione (1.0 equiv.) in AcOH (0.38 M) was added Fe (6.0 equiv.) and the reaction was stirred at room temperature for 2 h. Filtered, then washed with methanol and concentrated the filtrate. To the crude was added ethyl acetate and saturated NaHCO3, the organics were dried with Na2SO4, and concentrated to give 2-(3-(3-aminopyridin-4-yl)cyclohex-2-enyl)isoindoline-1,3-dione as a yellow thick gum in 96% yield. LC/MS=320.0 (M+H), LC=2.410 min.
