Reaction Steps
A mixture of 10-bromo-2-(1-(2-chlorophenyl)-1H-1,2,4-triazol-5-yl)-5,6-dihydrobenzo[f]imidazo[1,2-d][1,4]oxazepine (0.5 mmol), phenylboronic acid (200 mg, 0.75 mmol), Cs2CO3 (490 mg, 1.5 mmol) was stirred in dioxane and water (5:1, 3.0 mL) followed by the addition of Pd(dppf)Cl2 (30 mg). The reaction mixture was bubbled with N2 gas for 10 min, the reaction tube was sealed, and the contents were stirred at 130° C. under microwave irradiation for 30 min. The mixture was filtered through celite and the filtrate was concentrated and purified with prep-HPLC to give 563 (82 mg, 38%). 1H-NMR (DMSO, 400 MHz): δ 8.18 (s, 1H), 8.01 (s, 1H), 7.89 (s, 1H), 7.38-7.70 (m, 10H), 7.14 (d, J=7.6 Hz, 1H), 4.45-4.51 (m, 4H)
