A mixture of 7-bromo-4-(pyrimidin-2-ylmethyl)-3,4-dihydrobenzo[f][1,4]oxazepin-5(2H)-one (50 mg, 0.15 mmol), 2-(3-fluoro-4-(trifluoromethyl)phenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (52 mg, 0.18 mmol), cesium carbonate (146 mg, 0.45 mmol), 1,1′-bis(diphenylphosphino)ferrocene]dichloropalladium (10 mg, 0.015 mmol) was dissolved in a degassed mixture of DMF and water 3/1.5 (4.5 mL). The mixture was heated in microwave at 85° C. for 40 min. The mixture was poured into EtOAc and washed with water and brine. The organic layer was collected, dried over sodium sulfate and loaded onto silica gel. A flash column (5% MeOH in EtOAc) and reverse phase chromatography gave 7-(3-fluoro-4-(trifluoromethyl)phenyl)-4-(pyrimidin-2-ylmethyl)-3,4-dihydrobenzo[f][1,4]oxazepin-5 (2H)-one.
