The present technology relates to processes, mixtures and intermediates useful for making picolinamide fungicides. The picolinamide compounds are prepared by processes that include coupling together a 4-methoxy-3-acyloxypicolinic acid with key 2-amino-L-alaninate esters derived from substituted 2-phenylethanols.
本技术涉及用于制造吡啶甲酰胺类杀菌剂的过程、混合物和中间体。吡啶甲酰胺化合物是通过将4-甲氧基-3-酰氧基吡啶酸与来源于取代的2-苯基乙醇的关键2-氨基-L-丙氨酸酯偶联在一起的过程制备的。
