Synthesis Using Allylidenedihydropyridines. VIII. Facile Preparation of 2-Alkylthio-3-vinylpyrazolopyridines

Reactions of 1--2-methylpyridinium iodides with activated ethoxymethylene compounds in the presence of alkali gave the corresponding 1--2-allylidene-1,2-dihydropyridines in considerable yields, and their thermolyses in benzene afforded 2-alkylthio-3-vinylpyrazolopyridine derivatives.
