Reaction Steps

4-Methanesulfonyl-7-methoxy-6-nitro-1,3,4,5-tetrahydro-benzo[e][1,4]diazepin-2-one (0.57 g, 0.0018 mol) was hydrogenated in N,N-Dimethylformamide (40 mL, 0.5 mol) 10% Pd/C (10:90, Palladium:carbon black, 0.057 g) for 5 days. After the reaction was filtered and the filtrate evaporated. the residue was triturated with ether giving 6-Amino-4-methanesulfonyl-7-methoxy-1,3,4,5-tetrahydro-benzo[e][1,4]diazepin-2-one as a grey solid (0.50 g, 97%). Mp 232-233° C.; LCMS (m/e) 285 (M); 1H-NMR (DMSO, 400 MHz) δ 1H-NMR (DMSO, 400 MHz) δ 9.93 (s, 1H), 6.84-6.82 (d, 1H, J=8.59 Hz), 6.38-6.36 (d, 2H, J=8.33 Hz), 4.85 (s, 2H), 4.35 (s, 2H), 3.77 (s, 3H), 3.68 (s, 2H), 2.98 (s, 3H).
