Reaction Steps

To a solution of the aryloxybenzazepine (52 mg, 0.16 mmol) from Step B above in methanol (1 mL) was added L-tartaric acid (23.5 mg, 0.16 mmol) followed by slow addition of water (5 mL). The resultant solution was lyophilized overnight to give (−)-2-methyl-5-phenoxy-8-(pyridazin-3-yl)-2,3,4,5-tetrahydro-1H-benzo[c]azepine, tartrate salt (70 mg, 93%, AUC HPLC>99%) as a white solid: mp 98-100° C.; 1H NMR (CD3OD, 500 MHz) δ 9.17 (d, J=5.0 Hz, 1H), 8.21-8.18 (m, 2H), 8.08 (d, J=8.0 Hz, 1H), 7.82-7.79 (m, 1H), 7.68 (d, J=8.0 Hz, 1H), 7.28-7.25 (m, 2H), 7.06 (d, J=7.9 Hz, 2H), 6.95 (t, J=7.4 Hz, 1H), 5.75 (d, J=8.0 Hz, 1H), 4.92-4.84 (m, 1H), 4.51-4.48 (m, 1H), 4.41 (s, 2H), 3.95-3.85 (m, 1H), 3.57-3.55 (m, 1H), 2.88 (s, 3H), 2.46-2.38 (m, 2H); ESI MS m/z 332 [M+H].
