Procedure
A mixture of 1-Ethyl-7-methoxy-8-nitro-2-oxo-1,2,3,5-tetrahydro-benzo[e][1,4]diazepine-4-carboxylic acid benzyl ester (0.95 g, 0.0024 mol). and 10% Pd/C (10:90, Palladium:carbon black, 0.095 g) in Ethanol (100 mL, 2 mol) was hydrogenated on a Paar shaker for 1 day. The catalyst was filtered and the filtrate evaporated to give 8-Amino-1-ethyl-7-methoxy-1,3,4,5-tetrahydro-benzo-[e][1,4]diazepin-2-one as a tan solid (0.55 g). (98%). Mp 69-73° C.; LCMS (m/e) 236 (M+1); 1H-NMR (DMSO, 400 MHz) δ 6.75 (s, 1H), 6.61 (s, 1H), 4.83 (s, 2H), 3.76 (s, 3H), 3.74-68 (q, 2H, J=7.33 Hz), 3.58 (s, 2H), 2.97 (s, 2H), 1.05-02 (t, 3H, J=7.32 Hz).
