Procedure

9-bromo-2-(1-isopropyl-1H-imidazol-2-yl)-5,6-dihydrobenzo[f]imidazo[1,2-d][1,4]oxazepine (157 mg, 0.421 mmol), 2-methyl-1-(4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazol-1-yl)propan-2-ol (139.9 mg, 0.5258 mmol), and Tetrakis(triphenylphosphine)palladium(0) (68.05 mg, 0.05889 mmol) dissolved in Acetonitrile (2.66 mL, 50.9 mmol) and with dissolved 2.00 M of Potassium carbonate in Water (0.421 mL). The reaction mixture was degassed. The reaction was microwaved on 150 watts, 140° C. for 10 minutes. The reaction was cooled to r.t., extracted with ethyl acetate to give crude product purified by rHPLC to give 214.
