実験手順
Analogous to procedure 107b, 6-Methoxy-1,3,4,5-tetrahydro-benzo[b]azepin-2-one (700 mg, 3.66 mmol) was converted to 6-Methoxy-7-nitro-1,3,4,5-tetrahydro-benzo[b]azepin-2-one (380 mg, 44%), purified by ISCO chromatography. 1H-NMR (CDCl3) δ 8.12 (s, 1H), 7.79 (d, J=8.6 Hz, 1H). 6.85 (d, J=8.6 Hz, 1H), 3.95 (s, 3H), 2.95 (t, J=7.2 Hz, 2H), 2.44 (t, J=7.3 Hz, 2H), 2.31 (quint, J=7.2 Hz, 2H); LC/MS (ESI-pos) m/z 237.11 (M+H). Analogously, 6-Methoxy-9-nitro-1,3,4,5-tetrahydro-benzo[b]azepin-2-one was also isolated.
