Reaction Steps

To a 500 ml round bottom flask, 1-isopropyl-8-nitro-1,2,3,4-tetrahydro-benzo[e][1,4]diazepin-5-one (4.10 g, 16 mmoles), ethanol (300 ml), and palladium (320 mg) were added. The mixture was evacuated and charged with hydrogen (3 times). The reaction was stirred at room temperature under hydrogen balloon for the weekend (64 hrs). The solid was filtered through celite and washed with methanol. The solvent was then removed under vacuum to afford a brown oil. The desired product (2.15 g, 60% yield) was isolated via column chromatography with DCM and methanol as eluant (0 to 25% methanol). NMR 1H-(DMSO)-δ-7.32-7.52 (m, 1H), 7.00 (bs, 1H), 6.80 (bs, 1H), 4.80 (p, 1H), 3.40 (bs, 4H), 1.10 (d, 6H, J=6.58 Hz)
