Procedure
Copied from the source record, unedited
To a microwave vial containingN-(5-amino-2-methylphenyl)acetamide (0.120 g, 0.73 mmol), 5-chloro-7-(1-methyl-1H-imidazol-4-ylamino)pyrazolo[1,5-a]pyrimidine-3-carbonitrile (0.1 g, 0.37 mmol) ,sodium 2-methylpropan-2-olate (0.116 g, 1.21 mmol) and 2-Dicyclohexylphosphino-2',4',6'-tri-iso-propyl-1,1'-biphenyl (0.017 g, 0.04 mmol)was added DMA (2.2 ml). Vial was flushed with argon and to it was added Pd2(dba)3 (0.017 g, 0.02 mmol) and the reaction was heated in a MW reactor at 100 ° C for 60 min.Reaction was filtered, and filterate concentrated under reduced pressure to give dark red gum. This was suspended in 10% MeOH : DCM (10 ml) filtered and filterate concentrated to give crude solid. This was purified by flash column using 5-8% MeoH :DCM (1% NH4OH) to give 75 mg of pale yellow solid (EN0

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.
