(Chemical Equation Presented) Twenty-three 2-(substituted)phenyl-1,2,4- triazolo[1,5-a]pyridines have been synthesized by cyclo-additison reaction between N-amino methylpyridinium mesitylenesulfonates and substituted benzonitriles under the presence of po
Regioselection in 1,3-dipolar cycloadditions of 3-methylpyridine N-imide to aromatic carbonitriles. Synthesis of 2-aryl-8-methyl[1,2,4]triazolo [1,5-a]pyridines

1-Amino-3-methylpyridinium mesitylenesulfonate (3) reacts with aromatic nitriles in the presence of potassium hydroxide, undergoing 1,3-dipolar cycloaddition followed by elimination of H2 to give 2-aryl-8-methyl[1,2,4]triazolo[1,5-a]pyridines as the major products, rather than the 6-methyl isomers.
