The invention discloses a method for preparing an oxazoline insecticide arfamarin intermediate. The intermediate is 4-formyl-naphthalene-1-carboxylic acid, and compared with a synthesis route of US6613942B1, the synthesis route of the oxazoline insecticide arfamarin is simple. According to the method provided by some embodiments of the invention, through exploration, the reaction steps are shortened from three steps to one step, so the oxazoline insecticide arforlaana intermediate product with qualified purity can be obtained. The intermediate control steps are simplified, meanwhile, the product yield is increased, and industrial production is easier.
