A mixture of 7-bromo-4-quinolin-4-yl-2,3,4,5-tetrahydro-1,4-benzoxazepine (206 mg, 0.58 mmol), 5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1-methyl-1H-indazole (158 mg (0.58 mmol) (reagent preparation 50), potassium carbonate (320 mg, 2.32 mmol), and dichloro[1,1-bis(diphenylphosphino]ferrocenepalladium (II) dichloromethane adduct (50 mg, 0.06 mmol) in dimethoxyethane (4.0 mL) and water (1.0 mL) was degassed with nitrogen, and then stirred at 100° C. for 1 h. The reaction mixture was cooled to room temperature and partitioned between water and ethyl acetate. The mixture was filtered through celite and then the layers were separated. The organic layer was washed with brine, dried over anhydrous sodium sulfate, filtered and concentrated. Column chromatography on silica ((2S)-100% ethyl acetate in hexanes) afforded the title Compound (23 mg, 10% yield) as a yellow solid. 1H NMR (400 MHz, DMSO-d6): 8.63 d, 1H), 8.11 (s, 1H), 8.03 (m, 2H), 7.95 (d, 1H), 7.75 (m, 3H), 7.70 (m, 1H), 7.61 (dd, 1H), 7.51 (m, 1H), 7.11 (d, 1H), 7.02 (d, 1H), 4.61 (s, 2H), 4.39 (m, 2H), 4.09 (s, 3H), 3.84 (m, 2H); MS (EI) for C26H22N4O: 407 (MH+).
