Procedure
Copied from the source record, unedited
In a 25 mL round-bottomed flask (t=g) was 5-chloro-7-(cyclopropylamino)pyrazolo[1,5-a]pyrimidine-3-carbonitrile (40 mg, 0.17 mmol), Pd2(dba)3 (7.84 mg, 8.56 µmol), and [Reactants] in DMA (1.5 mL) ([VOLUME]) to give a black suspension.[Reactants] and N-(5-amino-2-methylphenyl)acetamide (28.1 mg, 0.17 mmol) were added. stirred at 110C for 2 days. TLC showed major is SM, small amount of product was formed/ did not workup LCMS showed 349 mass ??

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.
