The paper deals with direct quaternization of trimethylamine with 5-bromo-2-furylethylene derivatives Ia-Ig which contain strong electron acceptor substituents. New variants are described of the synthesis of 5-N,N-dimethylamino-2-furylethylene compounds III and 5-azido-2-furylethylene derivatives IV.
