Procedure
Copied from the source record, unedited
A mixture of N-(5-(1H-imidazol-2-yl)-2-methylphenyl)-4-((3-bromopyridin-2-yl)methoxy)benzamide (50 mg, 0.11 mmol), 1-methylpiperazine (32.4 mg, 0.32 mmol), Pd2(dba)3 (19.76 mg, 0.02 mmol) and BINAP (26.9 mg, 0.04 mmol), CS2CO3 (70.3 mg, 0.22 mmol) in DMA (5 mL) was stirred at 100 °C for overnight. LCMS didn't mornitor the desired 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.
