ABSTRACT:
The yield of Diels-Alder product obtained by reacting a haloprene with a 4-vinylpyridine is increased by conducting the reaction in the presence of a boron trifluoride catalyst, preferably a boron trifluoride etherate. The product obtained by the reaction, a mixture of 4-(chlorocyclohex-3-enyl)pyridines, is useful in the production of antibacterial 1-alkyl-1,4-dihydro-4-oxo-7-pyridinyl-3-quinolinecarboxylic acids.
