- 9% of (R)-2-(8-(3-Chloro-4-(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-chloro-4-(1H-1,2,4-triazol-1-yl)aniline (77 mg, 0.39 mmol), (R)-2-(8-chloro-2-phenyl-2,3-dihydropyrido[3,2-f][1,4]oxazepin-4(5H)-yl)ethanol (120 mg, 0.39 mmol), Palladium acetate (8.84 mg, 0.04 mmol), 2-(Dicyclohexylphosphino)biphenyl (13.80 mg, 0.04 mmol)and Cesium carbonate (385 mg, 1.18 mmol) were added to a microwave vial. 1,2-dimethoxyethane (2 mL) and EtOH (0.500 mL) were added. The reaction mixture was flushed with argon and the mixture was run in a microwave for 60 minutes at 100°C. The solvent was decanted and the solids were washed with DCM, 5ml. The solvent was then evaporated and the crude product was purified on prepHPLC yielding (R)-2-(8-(3-chloro-4-(1H-1,2,4-triazol-1-yl)phenylamino)-2-phenyl-2,3-dihydropyrido[3,2-f][1,4]oxazepin-4(5H)-yl)ethanol (16.00 mg, 8.78 %)

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.
