Procedure

A solution of 3-ethynyl-5-[3-fluoro-4-(3-trimethylsilanyl-propoxycarbonylmethyl)-phenylethynyl]-benzoic acid isopropyl ester (Intermediate 207, 0.15 g, 0.32 mmol) in anhydrous dimethysulfoxide (4 mL) was treated with tetra-n-ethyl ammonium fluoride (0.19 mL, 1.3 mmol) and the resulting reaction mixture was stirred at ambient temperature for 5 min. Water was added and the reaction mixture was extracted with ethyl acetate. The organic phase was washed with water and brine, dried over anhydrous sodium sulfate, filtered and evaporated to an oil that was purified by recrystallization from ethyl acetate/hexane to afford the title compound as a white solid (0.045 g, 38%).
