Ethyl 6-alkyl(aryl)-4-chloromethyl-2-methylpyridine-3-carboxylates react with ammonia and primary amines to give 6-substituted 3-alkyl(aryl)-1-methyl-1,2-dihydropyrrolo[3,4-c]pyridin-7-ones. The reactions with 4-aminopyridine yield ethyl 6-alkyl(aryl)-2-methyl-4-(4-pyridylaminomethyl)pyridine-3carboxylates.

Reactions of ethyl 6-alkyl(phenyl)-2-methyl-4-(chloromethyl)pyridine-3-carboxylates with O-nucleophiles afforded the corresponding 4-(phenoxymethyl)- and 4-(methoxymethyl)pyridine-3-carboxylates, and with N-nucleophiles provided ethyl 6-alkyl(phenyl)-2-methyl-4-[(dimethylamino)methyl]pyridine-3- carboxylates and also trisubstituted 1,2-dihydro-3H-pyrrolo[3,4-c]pyridin-3-ones.
