실험 절차

1,2,4,5-Tetrahydro-pyrido[2,3-e][1,4]diazepin-3-one (164 mg, 1.0 mmol) was dissolved into acetic acid (1 mL). Bromine (160 mg, 1.0 mmol) was added dropwise at room temperature and the solution was stirred overnight. Hexane (5 mL) was added and the orange precipitate was filtered and dried in vacuo. The title compound was isolated as an orange solid (190 mg, 78%). 1H NMR (300 MHz, DMSO-d6) δ 8.26 (t, J=5.7 Hz, 1H), 8.06 (d, J=2.1 Hz, 1H), 7.81 (d, J=2.1 Hz, 1H), 4.35 (d, J=5.7 Hz, 2H), 4.08 (s, 2H).
