Procedure
Copied from the source record, unedited
The aim of the reaction is test/optimization: 5-fluoro-4-(2-methyl-1-(tetrahydro-2H-pyran-4-yl)-1H-imidazol-5-yl)pyrimidin-2-amine (100 mg, 0.36 mmol), 4-(4-bromo-3-fluorobenzyl)morpholine (109 mg, 0.40 mmol), Palladium, 10% On Charcoal (115 mg, 0.11 mmol), Tri-o-tolylphosphine (49.4 mg, 0.16 mmol) and Sodium tert-pentoxide (79 mg, 0.72 mmol) were dissolved in toluene (1.5 mL) and heated to 110 °C under argon. The reaction was monitorred by HPLC. After 16 h 88 % conversion was achieved. The reaction was stopped and the mixture was discarded.

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.
