Procedure
Copied from the source record, unedited
(R)-8-chloro-4-methyl-2-phenyl-2,3,4,5-tetrahydropyrido[3,2-f][1,4]oxazepine (180 mg, 0,66 mmol), 3-methoxy-4-(3-methyl-1H-1,2,4-triazol-1-yl)aniline (134 mg, 0,66 mmol), Palladium acetate (14,71 mg, 0,07 mmol), 2-(Dicyclohexylphosphino)biphenyl (22,96 mg, 0,07 mmol) and Cesium carbonate (640 mg, 1,97 mmol) were mixed in DME (3 mL) in a microwave vial. EtOH (0,3 mL) was added and the mixture was run for 1 hour at 100°C in a microwave reactor. the reaction had to be run for an additional 2 hours with more catalyst and ligand added. the mixture was filtered and purified using flash chromatography 0-10% MeOH in DCM.

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.
