Abstract
2-Methyl-6-alkylpyridine(3)was obtained by the reaction of acylchlorination,amidation and cyclization from carboxylic acid.Three 6-alkyl-2-pyridinecarboxaldehydes(7)were synthesized by a four-step reaction of oxidation,ethylesterification,reduction and oxidation.A series of Schiff base derivatives were synthesized by the condensation of 7 with alkylanilines.The structures were characterized by UV-Vis,1H NMR,FT-IR and MS.
