The invention discloses a synthesis method of a fluopyram intermediate, and belongs to the field of organic synthesis of pesticides. The process comprises the following steps: by taking methanol amine as a starting raw material, carrying out esterification reaction on methanol amine and acetic anhydride in the presence of acetic acid to obtain methyl aminoacetate, and carrying out amidation reaction on methyl aminoacetate and o-trifluoromethyl benzoyl chloride to obtain N-acetoxymethyl-2-trifluoromethyl benzamide; and finally, carrying out a splicing reaction with diethyl 3-chloro-5-trifluoromethyl-2-pyridylmalonate, so as to obtain the 3-chloro-5-trifluoromethyl-2-pyridylethyl (diethyl ester)-2-trifluoromethyl benzamide. The method adopts a convergent synthesis route, has the characteristics of low raw material cost, high atom economy, high yield, simple process operation and the like, and is suitable for large-scale production.
