実験手順

A solution of {1-[4-(4-oxo-2-phenyl-8-trimethylsilanylethynyl-4H-chromen-3-yl)-phenyl]-cyclobutyl}-carbamic acid tert-butyl ester (51 mg, 0.091 mmol) in MeOH (2 mL) and DCM (1 mL) was treated with potassium carbonate (15 mg, 0.109 mmol) and the reaction stirred at RT for 3 h. The reaction mixture was quenched with water, diluted with EtOAc, washed with brine, dried (Na2SO4), filtered and concentrated in vacuo to give the title compound as a foamy solid (45 mg, 100%). 1H NMR (400 MHz, CDCl3): δ 8.27 (dd, J=7.7 and 1.6 Hz, 1H), 7.86 (dd, J=7.5 and 1.6 Hz, 1H), 7.48 (d, J=7.5 Hz, 2H), 7.41-7.30 (m, 5H), 7.25-7.19 (m, 3H), 5.06 (s, 1H), 3.47 (s, 1H), 2.65-2.27 (m, 4H), 2.14-2.00 (m, 1H), 1.91-1.76 (m, 1H), 1.37 (s, 9H).
