The invention discloses a method for preparing triclopyr 2-butoxyethyl ester. The method comprises the steps of dissolving sodium trichloro pyridinol by taking dimethyl formamide (DMF) as a solvent; dropwise adding ethyl chloroacetate and a catalyst and reacting to form an intermediate ethyl triclofenoxyacetate; carrying out filtering separation on the intermediate; and by taking methylbenzene asa solvent, adding butyl cellosolve and a catalyst to form the product triclopyr 2-butoxyethyl ester. The method has the advantages that the process flow is simple, the reaction time is short and the product can be obtained by only two-step reaction; in the reaction process, the amount of waste water is small and the process is highly environmentally friendly; a by-product produced by the reactionis ethanol which is safer and more environmentally friendly than methanol; and the total product yield is high and can be up to more than 88% and the product content can be up to more than 96%.
