Reaction Steps

2-(1-Isopropyl-1H-1,2,4-triazol-5-yl)-9-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-5,6-dihydrobenzo[f]imidazo[1,2-d][1,4]oxazepine (113 mg, 0.268 mmol), 1-(4-bromo-1H-imidazol-1-yl)-2-methylpropan-2-ol and 1-(5-bromo-1H-imidazol-1-yl)-2-methylpropan-2-ol (88.14 mg, 0.40 mmol), 1,1′-Bis(diphenylphosphino)ferrocenepalladium(II)chloride (21.90 mg, 0.027 mmol), 1,2-dimethoxyethane (3.0 mL, 29 mmol), and 1 M Cesium carbonate in water (0.54 mL, 0.5 mmol) were mixed in a microwave vial and microwaved at 140° C. for 15 minutes. Complete reaction by LCMS. Filtered through a paper filter followed by a silica plug. Concentrated in vacuo and purified by HPLC to give 202 (13.7 mg, 12% yield)
