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
100 °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

  • 78% of Dimethyl 5-morpholinoisophthalate.

Procedure

Copied from the source record, unedited

To a solution of dimethyl 5-bromoisophthalate (10 g, 36.62 mmol) in toluene (100 mL) where BINAP (2.5 g, 4.01 mmol), morpholine (4.4 g, 50.50 mmol), CESIUM CARBONATE (18 g, 55.25 mmol) and PALLADIUM(II) ACETATE (0.9 g, 4.01 mmol) added. The solution was heated to reflux under inert atm for 14h. The silvent was filtered and the filtrate was concentrated. The residue was purified by column chropmatography (Hep:EA) 1:1 to give dimethyl 5-morpholinoisophthalate (8.00 g, 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.
