3,5-Diacetyl- and 3,5-dicyano-1,2,6-trimethylpyridinium perchlorates are converted by recyclization into N,5-dimethylanilines and 2-methylaminopyridines, respectively.

Cyclocondensation of sodium nitromalone dialdehyde with different enamines gave 3-acetyl(benzoyl, cyano, cyclopropanoyl, carbethoxy)-2-methyl(phenyl)-5-nitropyridines. With the aim of increasing the yield of pyridines we have activated the nitromalonic dialdehyde through acylation of its enol form.
