To a solution of 3,3-bis-(3-methyl-thiophen-2-yl)-prop-2-en-1-ol (110 mg, 0.44 mmol) and triphenylphosphine (220 mg, 0.88 mmol) in THF was added, at room temperature and under nitrogen atmosphere, DEAD (153 mg, 0.88 mmol). The reaction mixture was stirred for 5 min after which (2-trifluoromethyl-4-mercapto-phenoxy)-acetic acid ethyl ester (70 mg, 0.25 mmol) was added over 15 min. The reaction mixture was stirred at room temperature for 100 hours. The reaction mixture was evaporated and the crude residue was purified on a Horizon using a methylene chloride:heptanes gradient as eluent. The desired {4-[3,3-bis-(3-methyl-thiophen-2-yl)-allylsulfanyl]-2-trifluoromethyl-phenoxy}-acetic acid ethyl ester was isolated in 75 mg (59%) yield.
