摘要

Processes for the preparation of a compound ", and for the preparation of 244 - 2 - dichloro - 5 - [4 - (difluorometil) - 4,5 - diidro - 3 - methyl - 5 - oxo - 1H 1,2,4 - Trizol - 1 - YL] - 4 - Fluoro ethyl benzenopropanoato, and.Process for the preparation of a compound "herbicide of 244 - 2 - chloro - 5 - [4 - (difluorometil) - 4,5 - diidro - 3 - methyl - 5 - oxo - 1h-1,2,4-triazole - 1 - YL] - 2.4 - = tituu00eddo - benzene - propyl ester alkyl.Through the reaction of 244 - acetyl - 5 - [4 - (difluorometil) - 4,5 - diidro - 3 - methyl - 5 - oxo - 1h-1,2,4-triazole - 1 - YL] - 2,4 - alkyl - benzene - distarch propanoate, the intermediary D,First with sodium hypochlorite, followed with a base, and the recovery of the herbicide.The intermediary D is prepared by the reaction of a 1 - (2,4 - distarch - 5 - halofenil) - 4 - difluorometil - 4.5 - diidro - 3 - methyl - 5 - the XO - 1h-1,2,4-triazole, intermediate B,With a alcanoato alkyl in the presence of a palladium catalyst and a tertiary amine.The agent B is prepared by reacting to a 1 - (phenyl - 2.4 - distarch) - 4 - difluorometil) - 4,5 - diidro - 3 - methyl - 5 - oxo - 1h-1,2,4-triazole with a halogenation agent in the presence of an acid.The substituents are independently selected 2,4 - halo, alkyl, alkoxy, nitro, or cicloalquila, heterciclila.
