HCl, generated in situ from 2,4,6-trichloro[1,3,5]triazine (TCT, cyanuric chloride), catalyzed a solvent free Hantzsch reaction at room temperature with enhanced reaction rates. The reaction conditions allow facile preparation of glycoconjugates of dihydropyridines under mild reaction conditions in high yields.
