4-isopropoxy-4′-methanesulfonyl-biphenyl-3-ol (30 mg) and potassium carbonate (20 mg) were dissolved in methylethylketone. Afterward, butane iodide (27 mg) and tetrabutylammoniumiodide (2-3 mg) was added one after another and heated for 24 hours at 40° C. After filtering just potassium carbonate, the residue was separated through a silica gel attributed chromatography (an eluting agent: ethylacetate/n-hexane=1/1, v/v). As a result, the present compound (30 mg, productive yield 88%) was obtained.
