Microwave irradiation of 2-carbethoxyacetamidine and an ethynyl ketone under acidic or basic conditions in ethanol at 150 °C for 1.5 hours facilitated Bohlmann-Rahtz pyridine synthesis to give highly substituted ethyl 2-aminonicotinates with total regiocontrol and in reasonable to excellent yield, following purification by immobilization upon an acidic resin.

A facile and efficient synthetic route to multi-substituted 2-aminopyridines has been developed via a formal [5C + 1N] annulation of readily available 2,4-pentadienenitriles with hydroxylamine (NH2OH) under very mild conditions, which involves
