To a solution of 2-chloro-5-(4-chlorophenyl)-10-methyl-7H-isoxazolo[5,4-c]pyrido[2,3-e]azepine (0.050 g, 0.145 mmol) in EtOH (1 mL) was added concentrated ammonium hydroxide (4.00 mL) and ammonium chloride (just enough to saturate the reaction) at room temperature. The reaction was heated to 100° C. overnight before the desired product was extracted using CH2Cl2 (repeated 4 times). The organic layers were combined, dried over Na2SO4 and concentrated to dryness. The residue was purified by flash chromatography (hexane/EtOAc 6:4 to 0:10) to give the title compound as a tan solid (0.008 g). LC/MS m/z 325 [M+H]+; 1H NMR (400 MHz, DMSO-d6) δ 7.43 (td, J=2.10, 8.70 Hz, 2H), 7.37 (td, J=2.10, 8.70 Hz, 2H), 7.24 (d, J=8.72 Hz, 1H), 6.77 (br. s, 2H), 6.38 (d, J=8.72 Hz, 1H), 4.61 (s, 2H), 2.56 (s, 3H).
