An easy, safe, solvent‐free and effective method for oxidative aromatization of Hantzsch 1,4‐dihydropyridines catalyzed by hypervalent iodine (IBD and HTIB) to corresponding pyridine derivatives in high yields within short span of time. All reactions were carried out just by grinding the two reactants.
