摘要:
(5-Nitro-2-furyl)vinylene-2-trimethylammonium bromide having the formula ##STR1## is suitable as a starting raw material for a plurality of syntheses of 5-nitro-2-furyl ethylene compounds possessing an antibacterial effect. The method of preparing the bromide involves reacting 1-(5-nitro-2-furyl)-2-bromoethylene with trimethylamine in an organic solvent medium at a temperature of from -10 .degree. to +50.degree. C.
