To a solution of 5-amino-2-nitrobenzoic acid (3.0 g, 16.4 mmol) in 40 ml of tetrahydrofuran was added 50 ml of borane-tetrahydrofuran complex (1.0 M solution in THF). The mixture was heated under reflux for one hour. The usual workup afforded the product. 1H NMR (400 MHz, DMSO-d6): 4.79 (2H, d, J=5.4 Hz), 5.37 (1H, t, J=5.4 Hz), 6.48 (1H, dd, J=9.0 Hz, J=2.5 Hz), 6.68 (2H, s), 6.99 (1H, d, J=2.5 Hz), 7.94 (1H, d, J=9.0 Hz).
