Reaction Steps
To a solution of 4-nitro isophthalic acid (4 g, 18.95 mmol) in MeOH (200 mL) was added Pd/C (20%) and the mixture was hydrogenated at RT over night. The reaction mixture was filtered through Celite and filtrate concentrated under vacuum to give 4-amino isophthalic acid in 60% as a solid.
