Procedure

5-(4-(2-(1-ethylcyclopentyloxy)-2-oxoethoxy)-3,5-dimethylphenyl)-5H-dibenzo[b,d]thiophenium bromide (2.00 g, 3.71 mmol) and sodium 3-hydroxyadamantane-acetoxy-1,1,2,2-tetrafluorobutane-1-sulfonate (1.61 g, 3.78 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 (4×200 mL), concentrated in vacuo and residual water removed via azeotrope with acetonitrile (2×200 mL) to afford the title compound (2.90 g, 91%) as a white solid. 1H NMR (500 MHz, (CD3)2CO) δ: 8.52 (d, J=8 Hz, 2H), 8.34 (d, J=8.5 Hz, 2H), 8.01 (t, J=7.5 Hz, 2H), 7.08 (t, J=7.5 Hz, 2H), 7.51 (s, 2H), 4.55 (s, 2H), 4.32 (t, J=6.5 Hz, 2H), 3.60 (brs, OH), 2.72 (tt, J=14, 6.5 Hz, 2H), 2.29 (s, 6H), 2.12-2.20 (m, 2H), 2.00 (q, J=7 Hz, 2H), 1.50-1.82 (m, 12H), 0.84 (t, J=7 Hz, 3H).
