The Experiment
In this experiment, isoquinoline 9 will be synthesised, according to Scheme 4. The Schiff base 8 is
prepared by the condensation of 3,4-dimethylphenethylamine 6 with 3-nitrobenzaldehyde 7. The
cyclisation of the Schiff base 8, under strong acid conditions, would provide the Hcl salt of isoquinoline
