The method and intermediates for the preparation of methylamides of C-methoxyiminocarboxylic acids of formula (I) (I), in which X means nitro, trifluoromethyl, halogen, C1-C4alkyl or C1-C4alkoxy, n means 0 or an integer in the range from 1 to 4, moreover, the radicals X may be different if n> 1, and Y means a C-organic radical carried out by the Pinner reaction of the interaction of acylcyanide of formula (II) (II) with alcohol and the subsequent interaction of the formed in the Pinner reaction ester of formula (IV) IV), with hydroxylamine to obtain an oxime of formula (V) (V), methylation of the oxime of formula (V) to the oxime ester of formula (VI) (VI), and subsequent reaction of the oxime ester of formula (VI) with methylamine. |
