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
130 °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

  • 0% of 6-benzylamino-3,4-dihydro-2H-isoquinolin-1-one.

Procedure

Copied from the source record, unedited

**Repeat 02915-84 but use NO solvent** In a 5 mL sealed MW* test tube was 6-bromo-3,4-dihydroisoquinolin-1(2H)-one (50 mg, 0.22 mmol), phenylmethanamine (97 µl, 0.88 mmol), BINAP (6.89 mg, 0.01 mmol) and palladium(II) acetate (2.483 mg, 0.01 mmol) combined to give a tan suspension. potassium tert-butoxide (24.82 mg, 0.22 mmol) was then added last. Placed test tube onto Smith MW* platform. Heated reaction to 70°C for 5 minutes. NO reaction!!! Added DMF (0.5 ml) and reheated reaction to 130°C for 15 mins. Took LCMS - no reaction, only unreacted SM!! 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.
