실험 절차

To a solution of {4-[4-ethoxy-3-methyl-3-(methylsulfonyl)-4-oxobutyl]phenyl}boronic acid (599 mg, 1.83 mmol) in methylene chloride (3 mL) was added phenol (86 mg, 0.91 mmol), pyridine (148 uL, 1.83 mmol) and copper (II) acetate (157 mg, 0.866 mmol). The mixture was stirred at ambient temperature under open atmosphere for 2 days. Silica gel was added and the mixture was concentrated to dryness and purified via silica gel chromatography eluting with ethyl acetate/heptanes to afford ethyl 2-methyl-2-(methylsulfonyl)-4-(4-phenoxyphenyl)butanoate as an oil. 312 mg. LCMS: (M+1) 377.2
