2Intramolecular proton transfer (IMPT)
The cation stabilizes via intramolecular proton transfer.
Intramolecular proton transfer
3Dehydration
The lone pair of electrons on the oxygen atom of the hydroxyl group abstracts a proton followed by dehydration and ring closure.
Dehydration reaction
4Resonance
The lone pair of electrons on the nitrogen atom delocalizes, which gives the corresponding resonating hybrids.
