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.

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

  • 59% of 2-[[2-[(1,3-dimethylpyrazol-4-yl)amino]-5-(trifluoromethyl)pyridin-4-yl]amino]-5-fluoro-N-methoxybenzamide.

Procedure

Copied from the source record, unedited

2-amino-5-fluoro-N-methoxybenzamide (2.60 g, 14.13 mmol), N-(1,3-dimethyl-1H-pyrazol-4-yl)-4-iodo-5-(trifluoromethyl)pyridin-2-amine (3.6 g, 9.42 mmol) (9,9-dimethyl-9H-xanthene-4,5-diyl)bis(diphenylphosphine) (0.545 g, 0.94 mmol) diacetoxypalladium (0.106 g, 0.47 mmol) and cesium carbonate (6.14 g, 18.84 mmol) were suspended in dioxane (40 mL). The reaction was degased, purged with argon (3 times) and heated to 100 °C overnight. The reaction mixture was allowed to cool to room temperature under stirring, diluted with ethyl acetate and the insolubles were removed by filtration, washed with EtOAc and the filtrate was concentrated. The crude product was purified by flash chromatography on silica gel eluting with 0 to 15% methanol in ethyl acetate/DCM (1/1). Fractions containing the most pa

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.
