4-Azulen-1-yl substituted 2,6-dimethyl-and 2,6-diphenyl-pyridines are obtained in good yields from the reaction of corresponding 4-azulen-1-yl-pyranylium salts and ammonium acetate in ethanol or starting from 4-chloro-2,6-diphenyl-pyranylium salts in two steps: reaction with azulenes followed by in situ treatment with ammonium acetate.
