The present invention relates to a process for preparing 4-{4-[({[4-chloro-3-(trifluoro-methyl)phenyl]amino}carbonyl)amino]phenoxy}-N-methylpyridine-2-carboxamide and its tosylate salt.

Process for the preparation of 4-{4-[({[4 chloro-3-(trifluoromethyl)phenyl]amino}carbonyl)amino]phenoxy}-N-methylpyridine-2-carboxamide

The present invention relates to a novel process for preparing 8-methoxy-3-quinolonecarboxylic acids which are antibiotics having potent antibacterial action.

Method for producing 8-methoxy-quinolinecarboxylic acids

The present invention relates to a process for the preparation of sulphonamide-substituted imidazotriazinones of the general formula (I)characterized in that compounds of the formula (II)are reacted with sulphuric acid and the products obtained are then reacted with thionyl chloride and converted in situ in an inert solvent using an amine into the compounds according to the invention and, if appropriate, reacted to give the corresponding salts, hydrates or N-oxides.

Process for the preparation of sulphonamide-substituted imidazotriazinones

A process for producing a compound of the formula (I) ##STR1## wherein Hal is chlorine or bromine, and R.sup.1 to R.sup.5 are, each independently, hydrogen, unsubstituted or substituted C.sub.1 -C.sub.10 -alkyl, or unsubstituted or substituted C.sub.6 -C.sub.10 -aryl;
