The reactions of β-azolyl enamines with azides proceeded under solvent-free conditions in the absence of base at 110°С by one of the possible routes, selectively forming 1,4-disubstituted 1,2,3-triazoles. The proposed reaction mechanism includes cycloaddition of the starting reagents, leading to 1,2,3-triazoline intermediates, followed by elimination of dimethylamine and the formation of aromatic triazole
