Procedure
Copied from the source record, unedited
8-chloro-4-methyl-2-(5-methylthiazol-2-yl)-2,3,4,5-tetrahydropyrido[3,2-f][1,4]oxazepine (140 mg, 0.47 mmol), 6-methoxy-5-(4-methyl-1H-imidazol-1-yl)pyridin-2-amine (106 mg, 0.52 mmol), 2-(DICYCLOHEXYLPHOSPHINO)BIPHENYL (16.59 mg, 0.05 mmol), PALLADIUM(II) ACETATE (10.63 mg, 0.05 mmol) and Cs2CO3 (308 mg, 0.95 mmol) were weighed into a microwave vial, the vial was capped and DME (4 mL) was added. The vial was flushed with argon and heated to 100°C in a microwave reactor for 1 h. The reaction mixture was diluted with dichloromethane and filtered and the solvents were evaporated. The residue was purified by column chromatography on Silica using gradient elution with methanol in dichloromethane (0-6 %) to give N-(6-methoxy-5-(4-methyl-1H-imidazol-1-yl)pyridin-2-yl)-4-methyl-2-(5-methylthiazol

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.
