A mixture of {4-[3,3-bis-(4-bromo-phenyl)-allylsulfanyl]-2-methyl-phenoxy}-acetic acid (described above) (231 mg, 0.421 mmol), 3-(trifluoromethyl)phenylboronic acid (203 mg, 1.07 mmol), KF (81 mg, 1.39 mmol), Pd2(dba)3 (23 mg, 0.025 mmol) and Pd(P(t-Bu)3)2 (26 mg, 0,051 mmol) was evacuated for air and kept under nitrogen. THF (5 ml) was added and the reaction mixture was stirred at 50° C. overnight. A saturated aqueous NH4Cl (5 ml) solution was added, and the mixture was extracted with methylene chloride (2×20 ml). The combined organic phases were dried an evaporated. The isolated products were further purified on HPLC using acetonitril:water (4:6) increasing to pure acetonitril as eluent. The title product was isolated as an E/Z mixture in 95 mg (37%) yield.
