Procedure
Copied from the source record, unedited
_The aim of this reaction is to synthesize material to check some ideas for route development and see if 'normal' Buchwald conditions is applicable here. IPC.s were taken and the reaction was monitored either by LCMS or HNMR (a crude sample dissolved in DMSO)._ 19/11-2015 14:00 A dried 250 mL rb-flask under nitrogen atmosphere was charged with 4-methylthiazol-2-amine (C0033995, BT250061) (6.61 g, 57.92 mmol), 6-bromopicolinic acid (C0013377, BT249846) (11.7 g, 57.92 mmol), TRIS(DIBENZYLIDENEACETONE)DIPALLADIUM(0) (C0007769, BT234652) (1.326 g, 1.45 mmol), dicyclohexyl(2',4',6'-triisopropyl-[1,1'-biphenyl]-2-yl)phosphane (C0018897, BT153355) (2.76 g, 5.79 mmol), SODIUM T-BUTOXIDE (C0006296, BT235115) (16.70 g, 173.76 mmol), Toluene (193 ml) was added and the suspension was heated and sti

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.
