Yield
- 28% of N-(3-methoxy-4-(4-methyl-1H-imidazol-1-yl)phenyl)-4-methyl-2-(pyridin-3-yl)-2,3,4,5-tetrahydropyrido[3,2-f][1,4]oxazepin-8-amine.
Procedure
Copied from the source record, unedited
[Reactants], Palladium(II) acetate (5.29 mg, 0.02 mmol), 2-(Dicyclohexylphosphino)biphenyl (8.26 mg, 0.02 mmol) and Cesium carbonate (0.230 g, 0.71 mmol) were placed in a microwave vial and flushed with argon. DME (2 mL) was added and the reaction mixture was run in the microwave at 100°C for 60 minutes. Reaction not complete. Added 0.1 eq of Palladium(II) acetate (5.29 mg, 0.02 mmol) and 0.1 eq of 2-(Dicyclohexylphosphino)biphenyl (8.26 mg, 0.02 mmol) and flushed with argon. Run in the microwave at 100°C for 60 minutes and the reaction was complete. The reaction mixture was filtrated through celite and concentrated. The crude product was purified by prep-HPLC. The solvent was evaporated and partitioned between sat. NaHCO3 and dichloromethane. The organic layer was separated, dried (MgSO4)

How to read this record
This is one experiment, not a rule. It says that on one occasion these species were combined under these conditions and this came out. It does not say the reaction will give the same result on your substrate, and nothing on the page has been generalised into a claim that it would.
The pathway is a separate question, kept on separate pages. A mechanism here is the canonical arrow pushing for a class, run on real structures and labelled rule-derived. It is not evidence, and this record is not a mechanism.
