Reaction Steps

To a mixture of (7-Methoxy-1-methyl-8-nitro-2-oxo-1,2,3,5-tetrahydro-benzo[e][1,4]diazepin-4-yl)-acetonitrile (0.47 g, 0.0016 mol) and Hydrazine hydrate (2.00 mL, 0.0411 mol) in Ethanol (10 mL, 0.2 mol) was added 10% Pd/C (10:90, Palladium:carbon black, 0.047 g) and reacted in an analogous manner to example 712. The reaction was filtered and evaporated. This product was chromatographed on SiO2 (13 g) with (20-1) DCM/MeOH giving (8-Amino-7-methoxy-1-methyl-2-oxo-1,2,3,5-tetrahydro-benzo[e][1,4]diazepin-4-yl)-acetonitrile as a tan solid (0.067 g, 16%). Mp 128-132° C.; LCMS (m/e)) 261 (M+1); 1H-NMR (DMSO, 400 MHz) δ 6.80 (s, 1H), 6.59 (s, 1H), 4.95 (s, 2H), 3.77 (s, 3H), 3.77-3.75 (d, 2H, J=9.35 Hz), 3.62 (s, 2H), 3.18 (s, 3H), 3.06 (s, 2H).
