- SYNTHESIS OF 3-HALO- AND 3-FORMYL-4-ALKYLPYRIDINES
-
In the presence of a catalytic amount of cuprous iodide, the addition of Grignard reagents to the 1-phenoxycarbonyl salts of 3-halopyridines gives 4-alkyl-3-halo-1-phenoxycarbonyl-1,4-dihydropyridines.The crude dihydropyridines were aromatized with o-chloroanil to give 4-alkyl-3-halopyridines.Several 4-alkylnicotinaldehydes were synthesized in a similar manner from the cyclic acetal (1,3-dioxolane) of 3-pyridinecarboxaldehyde.After aromatization with sulfur, the crude acetals were hydrolyzed with oxalic acid to give the desired pyridinecarboxaldehydes.
