[Reactants], 8-chloro-4-methyl-2-phenyl-2,3,4,5-tetrahydropyrido[3,2-f][1,4]oxazepine (0.120 g, 0.44 mmol), Palladium(II) acetate (9.81 mg, 0.04 mmol), 2-(Dicyclohexylphosphino)biphenyl (0.015 g, 0.04 mmol) and Cesium carbonate (0.427 g, 1.31 mmol) in DME (2.5 mL) were placed in a microwave vial and flushed with argon. The reaction mixture was then run in the microwave at 100°C for 1 hr. Reaction not complete. Run for another 30 minutes in the microwave. Still not complete. Added 0.1 eq of Palladium(II)acetate and 0.1 eq of 2-(Dicyclohexylphosphino)biphenyl and let the reaction mixture run in the microwave for additional 45 minutes. Reaction complete. The reaction mixture was filtrated through celite and the filtrate was concentrated. The crude product was purified by preparative chromatography giving 0.072 g (41%) of the product. N-(4-(1H-imidazol-1-yl)phenyl)-4-methyl-2-phenyl-2,3,4,5-tetrahydropyrido[3,2-f][1,4]oxazepin-8-amine
