In an evaporated schlenk flask kept under nitrogen atmosphere were added {4-[3,3-bis-(4-bromo-phenyl)-allylsulfanyl]-2-methyl-phenoxy}-acetic acid (297 mg, 0.54 mmol), phenylboronic acid (152 mg, 1.2 mmol), KF (104 mg, 1.79 mmol), Pd2(dba)3 (30 mg, 33 mmol) and Pd(P(t-Bu)3)2 (33 mg, 65 mmol). THF (6 ml) was added to the solid mixture keeping the mixture under nitrogen. The reaction mixture was stirred at room temperature for 1 h, followed by 4 h at 50° C. A saturated solution of ammonium chloride (5 ml) was added, and the mixture was extracted with dichloromethane (2×20 ml). The organic phases were dried and evaporated. The residue was purified by column chromatography (eluent: dichloromethane:THF (8:3)) to give the title compound in 155 mg (53%) yield.
