The present invention relates to N-carbomethoxy-N-methoxy-(2-chloromethyl)-aniline compounds of the formula I, wherein: n is 0, 1, 2 or 3, each R1 is independently selected from halogen, C1-C4-alkyl, C1-C4-haloalkyl, C1-C4-alkoxy or C1-C4-haloalkoxy. The invention also relates to processes and intermediates for preparing such compounds of formula I. The invention furthermore relates to processes for preparing 2-(pyrazol-3′-yloxymethylene)-anilides in which compounds of formula I are applied as precursors.
本发明涉及式I的N-羧甲氧基-N-甲氧基-(2-
氯甲基)-
苯胺化合物,其中:n为0、1、2或3,每个R1独立地选择自卤素、C1-C4烷基、C1-C4卤代烷基、C1-C4烷氧基或C1-C4卤代烷氧基。本发明还涉及制备式I化合物的方法和中间体。本发明还涉及应用式I化合物作为前体制备2-(
吡唑-3'-氧甲基)-苯甲酰胺的方法。
