Procedure

Into a round bottom flask, 2-{ethyl-[2-(2,2,2-trifluoro-acetylamino)-ethyl]-amino}-4-nitro-benzoic acid methyl ester (4.80 g, 13.2 mmol), methanol (60.0 mL, 1480 mmol) and sodium methoxide (0.86 g, 16 mmol) were added. The reaction was heated to 50 degree for 18 hours. TLC suggested 50% conversion. sodium methoxide (0.86 g, 16 mmoles) was added. The reaction was heated to reflux for 4 hours. The reaction was partitioned with water and DCM. The organic was separated, washed with Brine, and dried over magnesium sulfate. The solid was filtered and washed with DCM. The organic was removed under vacuum to afford 1-ethyl-8-nitro-1,2,3,4-tetrahydro-benzo[e][1,4]diazepin-5-one as a yellow solid (2.24 g, 71%). 1H-NMR (DMSO-D6, 400 MHz): δ 8.48 (t, 1H), 7.72 (d, 1H), 7.65 (d, 1H), 7.64 (s, 1H), 3.18-3.32 (m, 6H), 1.15 (t, 3H)
