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
80 °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

  • 75% of Ethyl 4-(2-fluoro-4-methylanilino)-7-(2-methoxyethoxy)-6-morpholin-4-ylquinoline-3-carboxylate.

Procedure

Copied from the source record, unedited

Reaction reference EN00057-06, EN02095-49, 67, 68, 74, 78, 90 In a 50 mL round-bottomed flask was ethyl 6-bromo-4-(2-fluoro-4-methylphenylamino)-7-(2-methoxyethoxy)quinoline-3-carboxylate (4.6911 g, 9.83 mmol), Morpholine (0.857 mL, 9.83 mmol), TRIS(DIBENZYLIDENEACETONE)DIPALLADIUM(0) (0.720 g, 0.79 mmol), and rac-2,2'-Bis(diphenylphosphino)-1,1'-binaphthyl (1.958 g, 3.14 mmol) in Dioxane (100 mL) to give a orange suspension. The reaction mixture was heated and stirred at 80°C (start 4pm). After stirring/heating overngiht, reaction is about 30% complete. Add rac-2,2'-Bis(diphenylphosphino)-1,1'-binaphthyl (1.958 g, 3.14 mmol) and TRIS(DIBENZYLIDENEACETONE)DIPALLADIUM(0) (0.720 g, 0.79 mmol). Continue heating/stirring. After heating and stirring for another 24hr, reaction is about 85% com

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.
