Procedure

4-amino-2-methoxybenzonitrile (72.9 mg, 0.49 mmol), (R)-2-(8-chloro-2-phenyl-2,3-dihydropyrido[3,2-f][1,4]oxazepin-4(5H)-yl)ethanol (150 mg, 0.49 mmol), Palladium acetate (11.05 mg, 0.05 mmol), 2-(Dicyclohexylphosphino)biphenyl (17.25 mg, 0.05 mmol)and Cesium carbonate (481 mg, 1.48 mmol) were added to a microwave vial. 1,2-dimethoxyethane (2 mL) and EtOH (0.500 mL) were added. The reaction mixture was flushed with argon and the mixture was run in a microwave for 60 minutes at 100°C. The solvent was decanted and the solids were washed with 5ml DCM. The solvent was evaporated and the crude product was purified on Si, 0-6% MeOH in DCM, yielding (R)-4-(4-(2-hydroxyethyl)-2-phenyl-2,3,4,5-tetrahydropyrido[3,2-f][1,4]oxazepin-8-ylamino)-2-methoxybenzonitrile (27.0 mg, 13.17 %)
