Reaction Steps

To a solution of 5-amino-2-(2-(dimethylamino)ethyl)-4-methyl-6-nitroisoindoline-1,3-dione (0.40 g, 1.37 mmol) in the mixture of methanol (8 mL) and acetic acid (0.4 mL) was added Pd/C (20 mg), and the resulting reaction mixture was hydrogenated for 2-3 h at 20-25 psi of hydrogen at rt. The reaction mixture was filtered through a pad of Celite and washed with methanol. The combined solvents were concentrated under vacuum to dryness. The crude product was used for the next step reaction without further purification. Mass (ESI, positive) m/z 263.0 [M+H]+.
