Procedure

Trifluoromethanesulfonic anhydride (0.350 mL) was added to a solution of 4,4′-(cyclobutane-1,1-diyl)diphenol (500 mg) and pyridine (0.505 mL) in MeCN (10 mL) at 0° C. The mixture was stirred at room temperature for 40 min. The mixture was neutralized with 1N HCl at 0° C. and extracted with EtOAc. The organic layer was separated, washed with water and brine, dried over anhydrous magnesium sulfate and concentrated in vacuo. The residue was purified by column chromatography (silica gel, eluted with EtOAc in hexane) to give 4-[1-(4-hydroxyphenyl)cyclobutyl]phenyl trifluoromethanesulfonate (160 mg) as colorless oil.
