- 10% of N-(6-Methoxy-5-(1-methyl-1H-pyrazol-4-yl)pyridin-2-yl)-4,6-dimethyl-2-(2,2,2-trifluoroethyl)-2,3,4,5-tetrahydropyrido[3,2-f][1,4]oxazepin-8-amine.
Procedure
Copied from the source record, unedited
6-methoxy-5-(1-methyl-1H-pyrazol-4-yl)pyridin-2-amine (104 mg, 0.51 mmol), 8-chloro-4,6-dimethyl-2-(2,2,2-trifluoroethyl)-2,3,4,5-tetrahydropyrido[3,2-f][1,4]oxazepine (150 mg, 0.51 mmol), Sodium tert-butoxide (73.4 mg, 0.76 mmol), rac-2,2'-Bis(diphenylphosphino)-1,1'-binaphthyl (22.19 mg, 0.04 mmol) and Tris(dibenzylideneacetone)dipalladium(0) (32.6 mg, 0.04 mmol) were added to a radley tube followed by toluene (6 mL). The reaction mixture was flushed with argon and the mixture was heated to 100°C and stirred overnight. The solids were filtered off and washed with DCM. The crude product was purified on prepHPLC yielding N-(6-methoxy-5-(1-methyl-1H-pyrazol-4-yl)pyridin-2-yl)-4,6-dimethyl-2-(2,2,2-trifluoroethyl)-2,3,4,5-tetrahydropyrido[3,2-f][1,4]oxazepin-8-amine (23.00 mg, 9.77 %)

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.
