Procedure
Copied from the source record, unedited
**Repeat 02915-84 but use MW* only. Reduce benzylamine from 4 to 2 eqs.** In a 10 mL sealed MW* test tube was 6-bromo-3,4-dihydroisoquinolin-1(2H)-one (100 mg, 0.44 mmol), phenylmethanamine (97 µl, 0.88 mmol), BINAP (13.77 mg, 0.02 mmol) and palladium(II) acetate (4.97 mg, 0.02 mmol) in DMF (500 mL) combined to give a tan suspension. potassium tert-butoxide (49.6 mg, 0.44 mmol) was then added last. Placed test tube onto Smith MW* platform. Heated reaction to 130°C for 15 minutes. Reaction know a cloudy pale amber. Took LCMS - there is NO product present, ALL SM!!! Placed sealed test tube in heated (130°C) oil bath over weekend. Took LCMS - all SM is consumed but NO desired product is seen!!! Discarded reaction.

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.
