실험 절차

2-aminomethyl-4-nitrobenzylamine (3.10 g, 17.1 mmol) was dissolved in tetrahydrofuran (300 mL) and a solution of N,N-carbonyldiimidazole (2.78 g, 17.1 mmol) in THF (40 mL) was added dropwise at room temperature over 30 minutes. The reaction was allowed to stir at room temperature for 72 hours. The solution was then poured over water (150 mL) and organics were extracted with ethyl acetate (3×100 mL). Combined organic extracts were dried over Na2SO4, filtered and reduced to afford 7-nitro-1,2,4,5-tetrahydro-benzo(e)(1,3)diazepin-3-one as a crude brown solid. Purification by flash column chromatography (0% MeOH/DCM-10% MeOH/DCM) afforded 2.5 grams of 7-nitro-1,2,4,5-tetrahydro-benzo(e)(1,3)diazepin-3-one as a yellow solid. LC/MS (ESI)=208.42 (M+H).
