Procedure
Copied from the source record, unedited
In a microwave tube, was Cs2CO3 (0.522 g, 1.60 mmol), N-(5-amino-2-methylphenyl)acetamide (0.132 g, 0.80 mmol), Pd2dba3 (0.037 g, 0.04 mmol),5-chloro-7-(oxetan-3-ylamino)pyrazolo[1,5-a]pyrimidine-3-carbonitrile (0.200 g, 0.80 mmol),di-tert- butyl(2',4',6'-triisopropyl-[1,1'-biphenyl]-2-yl)phosphine (0.034 g, 0.08 mmol). anhydrous DMA (2.0 mL) was added. The resulting mixture was bubbled through N2. Then the tube was capped. under microwave 145C for 30min. This reaction was repeated at 150mg again. The two batches were combined to workup The mixture was concentrated to dryness. Water (20 mL) was added. it was extracted with 10% MeOH in EtOAc, The combined organic phases were dried over Na2SO4, filtered and concentrated to dryness. It was purified by chromatography )Hex to 50% etAOc in H

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.
