| titleOfInvention | Process for the preparation of N-carboxyalkyl-3-fluoro-4-diaklylaminoanilines |
| abstract | Process for the preparation of N-carboxyalkyl-3-fluoro-4-dialkylaminoanilines, characterized in that in a first step 2-chloro-4,5-difluoronitrobenzene of the formula (I) with a secondary amine of formula (II) HNR 1 R 2 , wherein R 1 and R 2 are independently the same or different and represent an alkyl radical having 1 to 10 carbon atoms or together with the N atom to which they are attached Form a ring with 5 to 7 members, in the presence of a water-soluble amine, which forms hydrofluorides and hydrochlorides that are liquid at the reaction temperature and working-up temperature, in the presence or absence of a solvent, at -10 to 120 ° C., in a second step the second Chlorine-4-dialkylamino-5-fluoronitrobenzene-containing reaction mixture in the presence of the water-soluble amine in the presence of a noble metal catalyst with hydrogen at 30 to 150 ° C and 1 to 350 bar and in a third step the reaction mixture containing 3-fluoro-4-dialkylaminoaniline in the presence of the water-soluble amine with a chloroformate of the formula (IV) ClCO 2 R 3 , wherein R 3 is represents an alkyl radical with 1 to 10 carbon atoms or aralkyl radical with 7 to 20 carbon atoms, at 0 to 100 ° C. |
