Conditions

Temperature
100 °C

Procedure

4′-methanesulfonyl-biphenyl-3,4-diol (30 mg) and potassium carbonate (38 mg) were dissolved in methylethylketone. Afterward, ethane iodide (0.027 ml) was added and refluxed for 3 hours at 100° 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 (20 mg, productive yield 67%) was obtained.
