Procedure
Copied from the source record, unedited
The aim is optimization. (R)-2-chloro-6-methyl-8-phenyl-5,6,7,8-tetrahydropyrimido[5,4-f][1,4]oxazepine (29 mg, 0.11 mmol), 3-methoxy-4-(4-methyl-1H-imidazol-1-yl)aniline (21.38 mg, 0.11 mmol), Sodium tert-butoxide (15.16 mg, 0.16 mmol), rac-2,2'-Bis(diphenylphosphino)-1,1'-binaphthyl (9.17 mg, 0.01 mmol) and Tris(dibenzylideneacetone)dipalladium(0) (6.74 mg, 7.36 µmol) were added to a microwave vial then toluene (1 mL) was added. The reaction mixture was flushed with nitrogen and the mixture was heated to 120°C for 45 min. Small amount of product was formed. Abandoned.

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.
