Procedure
Copied from the source record, unedited
6-methoxy-5-(1-methyl-1H-pyrazol-4-yl)pyridin-2-amine (558 mg, 2.73 mmol), (R)-8-chloro-4-methyl-2-phenyl-2,3,4,5-tetrahydropyrido[3,2-f][1,4]oxazepine (750 mg, 2.73 mmol), Sodium tert-butoxide (394 mg, 4.09 mmol), rac-2,2'-Bis(diphenylphosphino)-1,1'-binaphthyl (119 mg, 0.19 mmol) and Tris(dibenzylideneacetone)dipalladium(0) (175 mg, 0.19 mmol) were added to a microwave vial followed by toluene (11 mL). The reaction mixture was flushed with nitrogen and the mixture was heated to 100°C and stirred overnight. The reaction was complete. The solids were filtered off and washed with ethyl acetate. The organic solution was extracted by sat NaHCO3 solution. The organic layer was dried over anhydrous sodium sulfate, filtered and concentrated. The crude product was purified by column chromatograph

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.
