To a solution of {3-[4-nitro-2-(2,2,2-trifluoro-ethylsulfanylmethyl)-phenoxy]-4-trimethylsilanylethynyl-phenyl}-acetic acid methyl ester (0.410 g, 0.8 mmol) in THF (3 mL) was added tetrabutylammonium fluoride (1M in THF; 1.2 mL, 1.2 mmol), and the reaction was stirred for 30 minutes at room temperature. Once no starting material was seen by analytical tlc, the mixture was worked-up with EtOAc and H2O, and the residue was purified by silica gel chromatography to give {4-Ethynyl-3-[4-nitro-2-(2,2,2-trifluoro-ethylsulfanylmethyl)-phenoxy]-phenyl}-acetic acid methyl ester.
