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.

Conditions

Temperature
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

  • 52% of 4-[[4-[(2,6-Dimethyl-3-pyridinyl)oxy]-2-pyridinyl]amino]-N-(2-methoxy-1-methylethyl)benzenesulfonamide.

Other recorded runs with the same starting material

No other run in the library makes this product. These runs of the same class start from one of the same reactants, which is the nearest company this record has.

Procedure

Copied from the source record, unedited

In a 10 mL microwave reactor 3-(2-chloropyridin-4-yloxy)-2,6-dimethylpyridine (100 mg, 0.43 mmol) and 4-amino-N-(1-methoxypropan-2-yl)benzenesulfonamide (104 mg, 0.43 mmol) were dissolved in DMA (3 mL) to give a brown solution.To the resultant solution Cesium carbonate (0.068 mL, 0.85 mmol) was added and sparged with nitrogen for 1 minute. Then Palladium(II) acetate (6.70 mg, 0.03 mmol) and 9,9-Dimethyl-4,5-bis(diphenylphosphino)xanthene (29.6 mg, 0.05 mmol) were added and the reaction mixture was sealed. The reaction was heated to150 °C for 25 minutes in the biotage microwave.The reaction was cooled to room temperature and LCMS shows reaction was completed. Reaction mixture was filtered through Celite Bed and washed with Dichloromethane. Filtrate was subjected to concentration to get DMA

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.
