Versuchsvorschrift

To a solution of 4-(benzyloxy)-1-(3-fluorobenzyl)-3-[(trimethylsilyl)ethynyl]pyridin-2(1H)-one (1.31 g, 3.2 mmol) in anhydrous acetonitrile (25 mL) at 0° C. was added tetrabutylammonium fluoride (0.611 g, 1.93 mmol). The reaction was stirred at 0° C. for 15 min then for 1 h at room temperature. The reaction was concentrated under reduced pressure and the residue was diluted with EtOAc and washed with water. The organic extracts were combined, dried over anhydrous Na2SO4, filtered, and concentrated under reduced pressure. The residue was purified by flash chromatography (silica gel) using EtOAc in hexanes (1:1 v/v). The appropriate fractions were combined and concentrated under reduced pressure to afford the desired product (0.779 g, 72%) as a gold solid.
