Reaction Steps

In a nitrogen atmosphere, 4-iodo-1,2,3-trifluorobenzene was dissolved into DMF, into which triethylamine, copper iodide (I), and tetrakistriphenylphosphine palladium (0) were added and heated to 55° C. Then, the DMF solution containing 1-hexine-3-ol was added dropwise for 20 minutes, and stirred for 3 hours. After the reaction mixture was poured into a sodium thiosulfate aqueous solution, and stirred for a while, an organic layer was separated, and an aqueous layer was extracted with toluene. After the extract and the organic layer were mixed together, washed using water, 10% hydrochloric acid twice, water, a saturated sodium hydrogen carbonate aqueous solution, and a saturated saline solution in that order, and dried using anhydrous magnesium sulfate, the solvent was evaporated under a reduced pressure. The residue was purified by column chromatography (silica gel, toluene/hexane) to obtain 1-(3-hydroxy-1-hexynyl)-2,3,4-trifluorobenzene.
