Abstract

acid amides of formula I which are intermediates for drugs and plant protection products are prepd. by reaction of the readily obtainable N-acetylamino-acetonitrile (II) with a nitrosating agent in an organic solvent e.g. acetic acid and alkyl nitrite or HCl gas and nitrous gases. The immediate product of the reaction is a C-hydroxyimino compd. which transforms readily to I.
