ABSTRACT:
A process for preparing 4-amino-2,5-di-(C.sub.1 -C.sub.4) alkoxybenzonitriles which comprises brominating 1-acylamino-2,5-dialkoxybenzenes, converting the 1-acylamino-2,5-dialkoxy-4-bromobenzenes so obtained by the reaction with copper-I-cyanide to the 4-acylamino-2,5-dialkoxy-benzonitriles and subsequently hydrolyzing the acylamino group; the known compounds are prepared by means of this process in better yields and in a technically simpler way.
