After 5-(9-bromo-5,6-dihydrobenzo[f]imidazo[1,2-d][1,4]oxazepin-2-yl)-1-isopropyl-1H-1,2,4-triazol-3-amine (400 mg, 1.03 mmol), 4-chlorophenylboronic acid (321 mg, 2.06 mmol), Pd(dppf)Cl2(84 mg, 0.1 mmol) and Cs2CO3 (403 mg, 1.23 mmol) were combined in a tube, dioxane and water (3:1, 20 ml) was added. The mixture was bubbled with N2 for 10 min. The mixture was sealed to heat in the microwave reactor at 130° C. for 30 min. The reaction mixture was filtered. The filtrate was concentrated and purified by HPLC to give 569 (74.9 mg, 17%) 1H NMR (DMSO, 400 MHz) δ 8.44 (d, J=8.4 Hz, 1H), 7.74 (d, J=9.2 Hz, 3H), 7.51-7.46 (m, 3H), 7.34 (s, 1H), 7.75-7.72 (m, 1H), 5.19 (s, 2H), 4.51 (s, 4H), 1.39 (d, J=6.8 Hz, 6H). LCMS (ESI) m/z 421.0 (M+H+)
