Procedure
Copied from the source record, unedited
8-chloro-4,6-dimethyl-2-(4-methylthiazol-2-yl)-2,3,4,5-tetrahydropyrido[3,2-f][1,4]oxazepine (185 mg, 0.60 mmol), 6-methoxy-5-(1-methyl-1H-pyrazol-4-yl)pyridin-2-amine (122 mg, 0.60 mmol), Pd2dba3 (13.67 mg, 0.01 mmol), BINAP (18.59 mg, 0.03 mmol) and SODIUM TERT-BUTOXIDE (92 mg, 0.96 mmol) were weighed into a microwave vial. toluene (5 mL) was added and the vial was capped and flushed with argon. The mixture was heated to 100°C in a microwave apparatus for 2 h. The reaction mixture was diluted with dichloromethane and filtered. The solvents were evaporated and the residue was purified by column chromatography on Silica using a gradient of increasing concentration of methanol, from 0 to 8 %, in dichloromethane to give 163 mg og the title product . The enantiomers were separated by HPLC usi

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.
