To 8-chloro-4,6-dimethyl-2-(2,2,2-trifluoroethyl)-2,3,4,5-tetrahydropyrido[3,2-f][1,4]oxazepine (300 mg, 0.51 mmol) in DME (4 mL) were 5-(4-methyl-1H-imidazol-1-yl)pyridin-2-amine (89 mg, 0.51 mmol), cesium carbonate (249 mg, 0.76 mmol), 2-(Dicyclohexylphosphino)biphenyl (17.84 mg, 0.05 mmol) and Palladium acetate (11.43 mg, 0.05 mmol) added. The reaction was heated to 110°C for 3*90min. The solids were filtered of and washed with DCM and IPA and discarded. The solvents were evaporated and the crude product was purified using first flash chromatography, 0-7% MeOH in DCM and the prepHPLC yielding 4,6-dimethyl-N-(5-(4-methyl-1H-imidazol-1-yl)pyridin-2-yl)-2-(2,2,2-trifluoroethyl)-2,3,4,5-tetrahydropyrido[3,2-f][1,4]oxazepin-8-amine (34.0 mg, 15.45 %)
