Vorschrift

Tert-butyl 5-(3-methoxyphenyl)-1,2,6b,7,8,10,11,11a-octahydro-9H-azepino[4,5-b][1,4]oxazino[2,3,4-hi]indole-9-carboxylate (502 mg, 70%) was prepared via coupling of tert-butyl 5-bromo-1,2,6b,7,8,10,11,11a-octahydro-9H-azepino[4,5-b][1,4]oxazino[2,3,4-hi]indole-9-carboxylate (671 mg, 1.64 mmol) with 3-methoxyphenyl boronic acid (374 mg, 2.46 mmol) as illustrated by the general procedure described in Example 534 Step C. CIMS (Methane) m/z=437 [MH]+. The corresponding hydrochloride salt of the title compound was formed from tert-butyl 5-(3-methoxyphenyl)-1,2,6b,7,8,10,11,11a-octahydro-9H-azepino[4,5-b][1,4]oxazino[2,3,4-hi]indole-9-carboxylate (500 mg) using the procedure described in Example 534 Step D. Then, this salt was free-based using 6 N NaOH, to give the title compound (395 mg, 99%). 1H NMR (CDCl3, 500 MHz) δ1.80-2.30 (m, 4H), 2.75-2.98 (m, 3H), 3.00-3.12 (m, 1H), 3.13-3.29 (m, 2H), 3.43-3.53 (m, 1H), 3.63-3.78 (m, 1H), 3.85 (s, 3H), 4.11 (brs, 1H), 4.41 (brs, 2H), 6.82 (dd, 1H, J=0.8, 8.3 Hz), 6.88 (s, 1H), 6.90 (s, 1H), 7.02 (s, 1H), 7.10 (d, 1H, J=8.3 Hz), 7.30 (t, 1H, J=8.3 Hz) ppm. CIMS (Methane) m/z=337 [MH]+.
