Reaction Steps
A mixture of 1-Ethyl-7-methoxy-8-nitro-1,3,4,5-tetrahydro-benzo[e][1,4]diazepin-2-one (0.42 g, 0.0016 mol), Ethyl bromide (0.244 mL, 0.00329 mol), Sodium iodide (0.0033 g, 0.000022 mol) and N,N-Diisopropylethylamine (1.14 mL, 0.00654 mol) in N,N-Dimethylformamide (4 mL, 0.05 mol) was stirred at room temperature for 22 hrs. The reaction was evaporated and the residue taken up in DCM/water, separated, washed, dried and evaporated to give 1,4-Diethyl-7-methoxy-8-nitro-1,3,4,5-tetrahydro-benzo[e][1,4]diazepin-2-one the product as a red oil. (0.44 g, 95%). LCMS (m/e) 294 (M+1); 1H-NMR (DMSO, 400 MHz) δ 7.95 (s, 1H), 7.45 (s, 1H), 3.95 (s, 3H), 3.87-81 (q, 2H, J=6.82 Hz), 3.61 (s, 2H), 2.98 (s, 2H), 2.89 (s, 1H), 2.73 (s, 1H), 2.59-52 (q, 2H, J=7.07 Hz), 1.08-1.00 (quin, 6H, J=7.07 Hz).
