In 10 m of DMF were poured 1.28 g (7.6 mmol) of methyl 2,4-dihydroxybenzoate and 1.05 g (7.6 mmol) of potassium carbonate, and 1.84 g (7.6 mmol) of farnesyl chloride was added thereto dropwise at room temperature. After the addition, the mixture was stirred at 60° C. for 3 hours and then poured into a 12% hydrochloric acid aqueous solution. Ethyl acetate was poured thereinto to conduct extraction. The resulting extract was washed with water and a saturated sodium chloride aqueous solution, dried over sodium sulfate, and concentrated. The resulting crude product was purified by column chromatography on silica gel to obtain 2.0 g (yield: 71%) of methyl 4-{(2E,6E)-3,7,11-trimethyl-2,6,10-dodecatrienyloxy}-2-hydroxybenzoate represeted by the following structural formula (hereinafter referred to as compound 37) as a colorless, clear and oily substance. The analytical results are shown below. ##STR58##
