Procedure
Copied from the source record, unedited
In microwave tube, added 5-chloro-7-(cyclopropylamino)pyrazolo[1,5-a]pyrimidine-3-carbonitrile (84mg), N-(1H-indol-6-yl)-N-methylacetamide (67 mg), Pd2(dba)3 (16 mg), (9,9-dimethyl-9H-xanthene-4,5-diyl)bis(diphenylphosphine) (20mg) cesium carbonate(129 mg) in anhydrous DMA (0.5mL). under microwave 150C for 30 min. the mixture was filtered. washed with MeOH. combinde organic solvent, dried to dryness. The residue solid was washed with MeOH to give about 22mg offwhite solid (product.

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.
