Drawn from the record's atom map: which bonds break and which form between the reactants and products the source listed. It shows a change in connectivity, not a simulated trajectory and not a mechanism.

What was in the flask

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

  • 21% of (R)-2-(8-(3-Methoxy-4-(3-methyl-1H-1,2,4-triazol-1-yl)phenylamino)-2-phenyl-2,3-dihydropyrido[3,2-f][1,4]oxazepin-4(5H)-yl)ethanol.

Procedure

Copied from the source record, unedited

3-methoxy-4-(3-methyl-1H-1,2,4-triazol-1-yl)aniline (67.0 mg, 0.33 mmol), (R)-2-(8-chloro-2-phenyl-2,3-dihydropyrido[3,2-f][1,4]oxazepin-4(5H)-yl)ethanol (100 mg, 0.33 mmol), Palladium acetate (7.37 mg, 0.03 mmol), 2-(Dicyclohexylphosphino)biphenyl (11.50 mg, 0.03 mmol) and Cesium carbonate (321 mg, 0.98 mmol) were added to a microwave vial. 1,2-dimethoxyethane (2 mL) was added. The reaction mixture was flushed with argon and the mixture was run in a microwave for 60 minutes at 100°C. No product was observed. Additional catalyst and ligand were added and the reaction was run 1h @ 100°C. Still no reaction occurred. EtOH (0.500 mL) was added and another h @ 100°C was executed. Full conversion into product was observed. The solids were filtered off and the solvent was concentrated. The crude

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.
