実験手順
To a solution of 2-(5-fluoro-2-((trimethylsilyl)ethynyl)phenyl)acetamide (A34) (0.239 g, 0.958 mmol) in DCM (10 mL) at 0° C. was added TBAF (1.0 M in THF; 1.44 mL, 1.44 mmol). The resulting mixture was stirred at 0° C. for 10 minutes, then poured into water (50 mL). The organic phase was separated and the aqueous layer was extracted with DCM (2×50 mL). The combined organic layers were washed with brine, dried (MgSO4) and the volatiles removed in vacuo. The residue was adsorbed onto silica gel then purified by column chromatography (Biotage Isolera, SiO2, 0-100% EtOAc in petroleum benzine 40-60° C.) to give the title compound A35 as a white solid (0.114 g, 67%); 1H NMR (400 MHz, d6-DMSO) δ 7.50 (dd, J=8.6, 5.9 Hz, 1H), 7.44 (s, 1H), 7.17 (dd, J=10.0, 2.7 Hz, 1H), 7.10 (td, J=8.6, 2.8 Hz, 1H), 6.99 (s, 1H), 4.32 (s, 1H), 3.61 (s, 2H). LCMS-A: rt 4.843 min; m/z 178 [M+H]+.
