実験手順

To a solution of (7bR,11aS)-N-[2-fluoro-3-(trifluoromethyl)phenyl]-1,2,7b,8,9,10,11,11a-octahydro-4H-[1,4]oxazepino[6,5,4-hi]pyrido[4,3-b]indol-6-amine free base from EXAMPLE 95 (41 mg, 0.1 mmol) in 5 mL tetrahydrofuran was added iodoethane (0.020 mL, 0.22 mmol) and sodium carbonate (21 mg, 0.22 mmol). The reaction was stirred at 60° C. for 3 h and then was cooled, quenched with water, extracted with ethyl acetate, washed with brine, dried (MgSO4) and concentrated. The residue was purified by preparative HPLC (C18 reverse phase column, elution with a H2O/CH3CN gradient with 0.5% TFA) and the product containing fractions were concentrated, free-based with aq ammonium hydroxide, extracted with chloroform, washed with brine, dried (K2CO3) and concentrated to afford the title compound of EXAMPLE 144. 1H NMR(CDCl3) δ: 7.15 (t, 1H, J=7.3 Hz), 7.05-6.95 (m, 2H), 6.91 (d, 1H, J=1.9 Hz), 6.77 (d, 1H, J=1.8 Hz), 5.73 (d, 1H, J=2.9 Hz), 4.63 (ABq, 2H, JAB=14.3 Hz), 4.25 (app d, 1H, J=12.9 Hz), 3.75 (app t, 1H), 3.43-3.36 (m, 2H), 3.27 (dd, 1H, J=12.8, 2.9 Hz), 2.97-2.80 (m, 2H), 2.75 (app t, 1H), 2.55-2.45 (m, 2H), 2.40-2.30 (m, 1H), 2.15-2.00 (m, 2H), 1.88 (app t, 1H), 1.15 (t, 3H, J=7.2 Hz). LRMS (ES)+: 436.4 (M+H)+.
