| titleOfInvention |
Method for producing n-(3-amino-4-fluorophenyl)- sulphonamides, n-(3-amino-4-fluorophenyl) carboxylic acid amides and n-(3-amino-4-fluorophenyl) carbamates |
| abstract |
The invention relates to a process for preparing N-(3-amino-4-fluoro-phenyl)-sulphonamides, N-(3-amino-4-fluoro-phenyl)-carboxamides or N-(3-amino-4-fluoro-phenyl)-carbamates of the general formula (I)in whichA represents SO2, CO or CO2 andR represents in each case optionally substituted alkyl or aryl, wherein1-fluoro-2,4-diamino-benzene of the formula (II)is reacted with sulphonyl chlorides, carbonyl chlorides or chlororformic esters of the general formula (III) in whichA and R are as defined abovein the presence of an acid acceptor and in the presence of a diluent at temperatures between -20° C. and +100° C. |
