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 tetrabutylammoniun fluoride (0.611 g, 1.93 mmol). The reaction was stirred at 0° C. for 15 minutes then for 1 hour at room temperature. The reaction was concentrated under reduced pressure and the residue was diluted with ethyl acetate and washed with water. The organic extracts were combined, dried over anhydrous Na2SO4 and concentrated under reduced pressure. The residue was purified by flash chromatography (silica gel) using ethyl acetate in hexane (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. 1H-NMR (CD3OD, 400 MHz) δ 7.73 (d, 1H, J=7.6 Hz), 7.43 (d, 2H, J=7.2 Hz), 7.35 (m, 4H), 7.09 (m, 3H), 6.45 (d, 1H, J=7.6 Hz), 5.27 (s, 2H), 5.13 (s, 2H), 3.78 (s, 1H); ES-HRMS m/z 334.1243 (M+H calculated for C21H17NO2F requires 334.1234).
