PROCEDURE FOR NITRATION OF ANILINE DERIVATIVES. |
| abstract |
The present invention relates to a process for the regio-selective nitration of high-grade alkyl esters of 4-alkanoylamino-3-alkyl-benzoic acids in position 5 within a mixture containing nitric acid, and the use of resulting products for the preparation of especially pharmaceutically active benzimidazole derivatives. |
