Procedure
Copied from the source record, unedited
TRIS(DIBENZYLIDENEACETONE)DIPALLADIUM(0) (22.18 mg, 0.02 mmol) was added to a degassed mixture of ethyl piperidine-4-carboxylate (0.105 mL, 0.68 mmol), (9,9-dimethyl-9H-xanthene-4,5-diyl)bis(diphenylphosphine)(xantphos) (28.0 mg, 0.05 mmol) and ethyl 1-(6-chloro-4-methylpyridin-3-yl)piperidine-4-carboxylate and sodium 2-methylpropan-2-olate (65.2 mg, 0.68 mmol) in toluene (3 mL). The resulting suspension was stirred at 100 °C for 20 hours under nitrogen. LCMS indicated little reaction so reaction abandoned.

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.
