Treatment of 3-substituted 1-(phenoxycarbonyl)-1,2-dihydropyridines with Vilsmeier reagent (POCl3/DMF) gave 3-substituted 5-formyl-1-(phenoxycarbonyl)-1,2-dihydropyridines, which were aromatized with hot sulfur to provide 5-substituted 3-pyridinecarboxaldehydes. The formylation of 4-substituted 1-(phenoxycarbonyl)-1,4-dihydropyridines and subsequent aromatization gave 4-substituted 3-pyridinecarboxaldehydes.
