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.

150 °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

  • 14% of 2-({5-Chloro-2-[(1,3-dimethyl-1H-pyrazol-4-yl)-amino]-4-pyridinyl}amino)-N-(methyloxy)benzamide.

Procedure

Copied from the source record, unedited

2-(2,5-dichloropyridin-4-ylamino)-N-methoxybenzamide (250 mg, 0.80 mmol), 1,3-dimethyl-1H-pyrazol-4-amine (134 mg, 1.20 mmol), Sodium tert-butoxide (115 mg, 1.20 mmol), 9,9-Dimethyl-4,5-bis(diphenylphosphino)xanthene (55.6 mg, 0.10 mmol) and BIS(DIBENZYLIDENEACETONE)DIPALLADIUM(0) (58.7 mg, 0.06 mmol) were suspended in dioxane (15 mL) and sealed into a microwave tube. The reaction was heated to 150 °C for 30 minutes in the microwave reactor and cooled to RT. Reaction not complete by LCMS so more 9,9-Dimethyl-4,5-bis(diphenylphosphino)xanthene (55.6 mg, 0.10 mmol), BIS(DIBENZYLIDENEACETONE)DIPALLADIUM(0) (58.7 mg, 0.06 mmol) and 1,3-dimethyl-1H-pyrazol-4-amine (134 mg, 1.20 mmol) were added and the reaction heated to 150 ºC for a further 30 minutes in the microwave reactor and cooled to RT.

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.
