The equation does not balance as written. That is usual for an experimental record: the source listed what it put in and what it measured, not a stoichiometric equation.

90 °C

Only the dimensions the source stated are listed. Anything absent here was not recorded, and it is not inferred from what the class usually needs.

Yield

  • 74% of 2-[[2-[(1,3-dimethylpyrazol-4-yl)amino]-5-(trifluoromethyl)-4-pyridyl]amino]-N,6-dimethoxy-benzamide.

Procedure

Copied from the source record, unedited

(9,9-dimethyl-9H-xanthene-4,5-diyl)bis(diphenylphosphine) (34.1 mg, 0.06 mmol), diacetoxypalladium (7.93 mg, 0.04 mmol), 2-amino-N,6-dimethoxybenzamide (131 mg, 0.67 mmol), N-(1,3-dimethyl-1H-pyrazol-4-yl)-4-iodo-5-(trifluoromethyl)pyridin-2-amine (150 mg, 0.39 mmol) and cesium carbonate (256 mg, 0.79 mmol) were weighed out in a µwave vial, sealed and dioxane (5 mL) was added. Argon was let to bubble in the mixture for 5 minutes. The reaction was stirred at 90 °C overnight. The reaction mixture was allowed to cool to room temperature, diluted with dichloromethane and MeOH, silica gel was added and the mixture was concentrated. The crude product was purified by flash chromatography on silica gel (25g) eluting with 0 to 5% methanol in ethyl acetate/DCM (1/1). The solvent was evaporated to dr

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.
