In order to obtain the important liquid crystal intermediate with trifluoromethyl substitutent, Sonogashira coupling reaction was used to synthesize the compound. In this paper, the intermediate was synthesized by 4'-Iodo-4-pentyl-biphenyl and trimethyl silyl acetylene (TMSA) as raw materials. During the synthesis, the optimum reaction conditions were obtained, that the mol ratio of 4'-Iodo-4-pentyl-biphenyl and trimethyl silyl acetylene is 1:2, the reaction temperature is 30 oC, and the reaction time is 10 h.
