PROCESS FOR PREPARING A DERIVATIVE OF ALPHA-METHOXYIMINOCARBOXYLIC ACID METHYLAMIDE AND INTERMEDIATES FOR SUCH PROCESS

A process and intermediates for preparing alpha -methoxyiminocarboxylic acid methylamides (I) by Pinner reaction of a cyanoketone (II) with an alcohol and subsequent reaction of the resulting ester (IV) with hydroxylamine to give the oxime (V), methylation of (V) to give the oxime ether (VI) and sub...
