To a mixture of 9-chloro-8-methoxy-2,3,4,5-tetrahydro-1H-2-benzazepin-1-one (132a) and 7-chloro-8-methoxy-2,3,4,5-tetrahydro-1H-2-benzazepin-1-one (132b) (35.0 mg, 0.150 mmol) in DMF (5 mL) was added 2-(benzyloxy)-3-(chloromethyl)-4,6-dimethylpyridine (Cpd Z, 47.1 mg, 0.180 mmol). The reaction mixture was heated at 80° C. for 24 hours. The reaction mixture was poured into a NaOAc-HOAc buffer (5 mL) and extracted with EtOAc (2×10 mL). The combined organic layers were dried over sodium sulfate and concentrated under vacuum. The resulting brown oil was dissolved in MeOH (1 mL) and HCl (3 M in n-butanol, 0.05 mL) was added. The reaction mixture was heated at 70° C. for 24 hours. The solvent was removed in vacuum and the residue was purified by preparative HPLC to give the title compounds (Example 132-A, first eluting product, 20 mg, 36%); 1H NMR (400 MHz, methanol-d4) δ 7.09-7.14 (m, 1H), 7.05-7.10 (m, 1H), 6.13 (s, 1H), 4.89 (s, 1H), 4.71-4.79 (m, 1H), 3.88 (s, 3H), 3.38 (dd, J=5.93, 14.86 Hz, 1H), 2.92-3.01 (m, 1H), 2.57-2.73 (m, 2H), 2.35 (s, 3H), 2.25 (s, 3H), 2.06-2.14 (m, 1H), 1.53-1.64 (m, 1H); MS 361.1 [M+1]; and (Example 132-B, second eluting product, 4 mg, 7%); 1H NMR (400 MHz, methanol-d4) δ 7.26 (s, 1H), 7.22 (s, 1H), 6.13 (s, 1H), 4.78 (s, 2H), 3.91 (s, 3H), 3.26-3.29 (m, 2H), 2.63 (t, J=7.09 Hz, 2H), 2.34 (s, 3H), 2.26 (s, 3H), 1.78 (t, J=6.66 Hz, 2H); MS 361.1 [M+1]; as a white solids.
