| titleOfInvention | A PROCEDURE FOR THE PREPARATION OF DERIVATIVES OF IMIDA-ZOLIO. |
| abstract | Improvements introduced in the main patent object No. 391.801 by: A process for the preparation of imidazolium derivatives, characterized in that they consist of: (a) subjecting a compound of formula III to oxidation: **(See formula)** where R1 and R2, together with the two atoms of the imidazole ring, form a benzene ring, R3 represents hydrogen, aryl or substituted aryl, R4 represents An alkyl group of 1 to 6 carbon atoms and X- represents a physiologically acceptable anion, to link two molecules of the compound of formula III to each other and thus form a tetrazine and, if desired, convert the X- anion to another X-anion within the meaning given above, or (b) convert a compound of formula II, where X represents a bromide ion, and a compound where X represents a pharmaceutically acceptable anion other than bromide.
