Procedure
Copied from the source record, unedited
In a 50 mL round-bottomed flask a TRIS(DIBENZYLIDENEACETONE)DIPALLADIUM(0) (0.115 g, 0.13 mmol),POTASSIUM TERT-BUTOXIDE (0.282 g, 2.51 mmol)and BINAP (0.157 g, 0.25 mmol) in dry 1,4-dioxane (10 mL) was mixed under N2.Followed by 6-chloro-N-cyclohexylnicotinamide (.300 g, 1.26 mmol) and 4-aminobenzonitrile (0.178 g, 1.51 mmol) was added and resulting mixture(dark brown) was heated at 100oC for 3 hrs.LCMS analysis showed the formation of required product.Reaction stopped,crude was passed through celite and washed with dioxane and finally with methanol.The filtrate was dried and dissolved in 3 ml DMSO for Waters MS Purification system.Pure fractions collected and concentrated.A White solid obtained as a product 6-(4-cyanophenylamino)-N-cyclohexylnicotinamide (0.040 g, 9.93 %).32 mg of above p

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.
