実験手順

5-(3,5-dimethyl-4-(2-oxo-2-(2-phenylpropan-2-yloxy)ethoxy)phenyl)-5H-dibenzo[b,d]thiophenium bromide (7.00 g, 12.5 mmol) and triethylammonium 1,1-difluoro-2-(methacryloyloxy)ethanesulfonate (4.21 g, 12.7 mmol) were dissolved in dichloromethane (100 mL) and water (100 mL) and stirred at room temperature overnight. The dichloromethane layer was separated and the aqueous phase washed with dichloromethane (3×100 mL). The combined organic layers were washed with water (4×100 mL), concentrated in vacuo and residual water removed via azeotrope with acetonitrile (2×100 mL) to afford the title compound (7.07 g, 80%) as a white solid. 1H NMR (300 MHz, (CD3)2CO) δ: 8.53 (d, J=7.8 Hz, 2H), 8.37 (d, J=7.8 Hz, 2H), 8.03 (t, J=7.8 Hz, 2H), 7.82 (t, J=7.8 Hz, 2H), 7.52 (s, 2H), 7.40 (d, J=8.1 Hz, 2H), 7.32 (t, J=8.1 Hz, 2H), 7.26 (t, J=8.1 Hz, 1H), 6.12-6.19 (m, 1H), 5.68-5.71 (m, 1H), 4.76 (t, J=15.6 Hz, 2H), 4.66 (s, 2H), 2.28 (s, 6H), 1.94 (s, 3H), 1.77 (s, 6H).
