| titleOfInvention | Process for the preparation of 3,4-dialkoxyanilines |
| abstract | A new process for the production of 3,4-dialkoxyanilines in which the two alkyl groups are different from each other is disclosed. The process comprises the stepwise introduction of the alkyl groups in different stages of the process by converting pyrocatechol into its monoalkyl ether, coupling said monoalkyl ether with a phenyldiazonium salt, alkylating the 3-alkoxy-4-hydroxy-azobenzene obtained to form 3,4-dialkoxyazobenzene and reductively cleaving the latter to the corresponding 3,4-dialkoxyaniline. The 3,4-dialkoxyanilines obtainable by the new process are valuable intermediates for the preparation of 4-hydroxy-6,7-dialkoxy-3-quinoline carboxylic acid esters which are excellent coccidiostats. |
