The mixture was capped and flushed with argon. 2-(8-chloro-2-(1,3-dimethyl-1H-pyrazol-5-yl)-2,3-dihydropyrido[3,2-f][1,4]oxazepin-4(5H)-yl)acetonitrile (0.201 g, 0.63 mmol) in 1,2-dimethoxyethane (5 mL) was added, the reaction mixture was flushed with argon and the mixture was run in a microwave for 60 minutes at 100°C. No product, only unreacted startingmaterial. Added 1 eq CsCO3, and 0.1 eq ligand and palladium acetate, flushed with argon and run in the microwave at 100°C for 60 min. Reaction complete. The reaction mixture was filtrated through Celite and washed with dichloromethane. The filtrate was concentrated and the crude product was purified by preparative chromatography. The productcontaining fractions were pooled, concentrated and the residue was partitioned between sat. NaHCO3 (aq) and dichloromethane. The organic layer was separated by a Phase Separator and concentrated giving 2-(2-(1,3-dimethyl-1H-pyrazol-5-yl)-8-(4-(2-methyl-1H-imidazol-1-yl)phenylamino)-2,3-dihydropyrido[3,2-f][1,4]oxazepin-4(5H)-yl)acetonitrile (0.041 g, 14.26 %)
