The invention discloses a method for synthesizing herbicide pretilachlor by a one-pot method, which comprises the following steps of: reacting 2,6-diethylaminobenzene with strong base in a nonprotonic solvent to generate amino sodium salt; then reacting the amino sodium salt with chloroethyl propyl ether to generate pretilachlor intermediate 2,6-diethyl-N-(2-propoxyethyl) phenylamine; and leadingthe intermediate 2,6-diethyl-N-(2-propoxyethyl)phenylamine not subjected to separation and chloroacetic chloride to carry out acylation reaction in the same reactor to obtain pretilachlor. The invention has the advantages of high reaction selectivity, high yield, short process flow, high utilization ratio of raw materials, reduced production cost and higher productive and practical value.
