- 16% of (R)-N-(6-methoxy-5-(4-methyl-1H-imidazol-1-yl)pyridin-2-yl)-4-methyl-2-phenyl-2,3,4,5-tetrahydropyrido[3,2-f][1,4]oxazepin-8-amine.
Procedure
Copied from the source record, unedited
A solution of (R)-8-chloro-4-methyl-2-phenyl-2,3,4,5-tetrahydropyrido[3,2-f][1,4]oxazepine (83 mg, 0.30 mmol) and 6-methoxy-5-(4-methyl-1H-imidazol-1-yl)pyridin-2-amine (62.0 mg, 0.30 mmol) in DME (3 mL) was added to a microwave vial containing palladium(II) acetate (6.82 mg, 0.03 mmol), 2-(Dicyclohexylphosphino)biphenyl (10.64 mg, 0.03 mmol) and CS2CO3 (297 mg, 0.91 mmol) under an athmosphere of argon. The resulting mixture was heated to 100°C in a microwave apparatus for 2 h. The reaction mixture was diluted with dichloromethane and methanol and filtered through a plug of Celite. The solvents were evaporated and the residue was purified by HPLC to give 21 mg of the title product (16 % Yield).

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.
