Procedure
Copied from the source record, unedited
EN04773-53, _Buchwald coupling, toluene and bromide_ The indole from 4773-25, 1-(benzyloxy)-3-bromobenzene,Pd2(dba)3, JohnPhos and KOtBu were dissolved in toluene. The mixture was warmed at 100 °C for 2h. Ca 60% conversion according to LCMS (product at 2.31 min). This conversion rate seemed faster than for the corresponding aryliodide. Big bacth was performed in 4773-54.

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.
