The overall yield was 43.6%.The yield of reduce of ester was increased nearly one times than the past method because of KBH4-LiCl as the reducing agent instead of NaBH4. Changing the reaction conditions of bromization, the one-way yield enhanced 30%. The yield of reduce of the bromide was added by one times by improving the process. Tefluthrin was achieved by the catalytic esterification of DCC and DMAP.

优化后工艺对四氟对苯二甲酯的还原采用了廉价高效的还原试剂KBH4-LiCl，使收率比NaBH4法提高了近一倍；对溴化反应条件进行了优化，单程收率提高了30%；对溴化物还原条件的优化，使其收率提高了近一倍；采用了催化剂DCC和DMAP合成了最终产品七氟菊酯。
