Procedure
Copied from the source record, unedited
BINAP (0.432 g, 0.69 mmol) and Pd2(dba)3 (0.24 g, 0.26 mmol) were dissolved in toluene (10 mL) and to this (S)-N-(1-amino-3-methylbutan-2-yl)-2,4,6-trimethylbenzenesulfonamide (0.856 g, 3.01 mmol) and 4-bromo-1-(4-fluorophenyl)-1H-indazole (0.876 g, 3.01 mmol) was added followed by sodium tert-butoxide (0.434 g, 4.51 mmol). The reaction mixture was degassed and the reaction tube was filled with nitrogen before it was heated at 110°C for 2h. LCMS indicated 55% product and just a small amout of starting materials remained. The reaction was partitioned between EtOAc and water. The layers were separated and the aqueous extracted twice with EtOAc. The organic extracts were combined, filtered through a fine sinter funnel to remove a grey ppte and then dried using a phase separator cartridge. The

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.
