40% In 2,4-dichlorophenoxyacetic acid dimethylamine; mineral oil; The 4-hydroxy-4-[3-(naphth-2-ylthio)-5-trifluoromethylphenyl]tetrahydropyran used as a starting material was obtained as follows: Sodium hydride (60% w/w dispersion in mineral oil; 0.5 g) was added portionwise to a mixture of 2-naphthalenethiol (1.42 g) and DMA (30 ml) and the mixture was stirred at ambient temperature for 1 hour. A solution of <strong>[130723-13-6]1-bromo-3-fluoro-5-trifluoromethylbenzene</strong> (2.43 g) in DMA (10 ml) was added and the mixture was stirred at ambient temperature for 16 hours. The mixture was partitioned between ethyl acetate and water. The organic layer was washed with brine (50 ml), dried (MgSO4) and evaporated. The residue was purified by column chromatography using hexane as eluent. There was thus obtained 3-bromo-5-trifluoromethylphenyl 2-naphthyl sulphide (1.37 g, 40%), as an oil. A solution of the product so obtained in THF (10 ml) was cooled to -60 C. and n-butyl-lithium (1.6M in hexane; 2.3 ml) was added dropwise.

YieldReaction ConditionsOperation in experiment
With iodine; magnesium; In tetrahydrofuran; water; Step A Synthesis of 3-fluoro-5-trifluoromethylphenylboronic acid as an intermediate A crystal of iodine and 0.5 gram (0.021 mole) of magnesium turnings were placed in a reaction vessel containing 10 mL of tetrahydrofuran. To this was added dropwise 2 mL of a solution of 5.0 grams (0.021 mole) of <strong>[130723-13-6]3-fluoro-5-trifluoromethylphenyl bromide</strong> in 65 mL of tetrahydrofuran. The Grignard formation was initiated by warming the reaction vessel to about 45 C. The remaining <strong>[130723-13-6]3-fluoro-5-trifluoromethylphenyl bromide</strong>--tetrahydrofuran solution was added portionwise at a rate which maintained gentle reflux of the reaction mixture. In a second reaction vessel, 40 mL of tetrahydrofuran was cooled to -78 C., and 2.3 mL (0.021 mole) of trimethyl borate was added dropwise as the Grignard reagent of <strong>[130723-13-6]3-fluoro-5-trifluoromethylphenyl bromide</strong> prepared above was transferred into the second reaction vessel using a cannula. The temperature of the reaction mixture was maintained below -60 C. during the additions. Upon completion of the additions, the reaction mixture was again cooled to -78 C., where it was stirred for about 45 minutes. After this time, the reaction mixture was allowed to warm to ambient temperature. The reaction mixture was then poured into about 200 mL of water and was made acidic with aqueous 5% hydrochloric acid. The mixture was extracted with four 100 mL portions of ethyl acetate. The combined extracts were dried with magnesium sulfate and filtered. The filtrate was concentrated under reduced pressure, yielding 3.3 grams of 3-fluoro-5-trifluoromethylphenylboronic acid, mp 167-168 C. The NMR spectrum was consistent with the proposed structure.
