Preparation method of substituted phenoxy benzylamine compound and preparation method of pyrazole carboxamide compound

The invention discloses a preparation method of a substituted phenoxy benzylamine compound. P-halobenzonitrile is taken as an initial raw material, R'OH is taken as a solvent in the presence of R'OM, the substituted phenoxy benzylamine compound is obtained through hydrogen reduction, and the preparation method has the advantages of high yield and high purity. The invention also discloses a preparation method of pyrazole carboxamide. The preparation method of pyrazole carboxamide comprises the following steps: salifying the substituted phenoxy benzylamine compound, and reacting with a substituted pyrazole acyl chloride compound to prepare the pyrazole carboxamide compound at an expected high yield. The preparation methods provided by the invention have the advantages of high product purity, high yield, low solvent loss and low production cost.

Method for preparing pyrazole amide compounds by using microreactor

The invention relates to a method for preparing pyrazole amide compounds by using a microreactor. Specifically, a solution obtained by dissolving a compound shown in a formula (A) in an organic solvent and a solution obtained by dissolving a compound shown in a formula (B) in an organic solvent are mixed through a micro-mixer and then input into a micro-channel reactor for reaction, and a reactionsolution is subjected to aftertreatment to prepare the pyrazole amide compound shown in a formula (C). According to the technical scheme, the micro-channel reactor is adopted, so that the mass transfer and heat transfer efficiency is effectively improved, the reaction rate can be effectively increased, the reaction time is greatly shortened, and the production efficiency is improved; continuous production operation can be achieved, the product quality stability is improved, the equipment integration degree is high, and the occupied space can be reduced; an acid-binding agent does not need tobe additionally added, product aftertreatment is simple, no waste salt is generated, and the product is high in yield, high in purity, safe and environmentally friendly.
