Reaction Steps

5-(3,5-dimethyl-4-(2-oxo-2-(2-phenylpropan-2-yloxy)ethoxy)phenyl)-5H-dibenzo[b,d]thiophenium bromide (1.8 g, 3.21 mmol) and sodium 3-hydroxyadamantane-acetoxy-1,1,2,2-tetrafluorobutane-1-sulfonate (1.44 g, 3.37 mmol) were dissolved in dichloromethane (100 mL) and water (100 mL) and stirred at r.t. overnight. The dichloromethane layer was separated and the aqueous phase washed with dichloromethane (3×100 mL). The combined organic layers were washed with water (6×200 mL) and concentrated in vacuo to afford the title compound (2.44 g, 86%) as a white solid. 1H NMR (500 MHz, ((CD3)2SO) δ: 8.53 (d, J=8 Hz, 2H), 8.35 (d, J=8 Hz, 2H), 8.03 (t, J=7 Hz, 2H), 7.83 (d, J=8 Hz, 2H), 7.51 (s, 2H), 7.40 (d, J=8 Hz, 2H), 7.31 (dt, J=8, 0.5 Hz, 2H), 7.24 (dt, J=7.5, 1 Hz, 1H), 4.65 (s, 2H), 4.31 (t, J=6.5 Hz, 2H), 2.80-2.82 (m, 2H), 2.65 (tt, J=14, 6.5 Hz, 2H), 2.29 (s, 6H), 1.72-1.81 (m, 10H), 1.65-1.67 (m, 4H), 1.56-1.59 (m, 2H).
