Procedure
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 4-((4R)-4-((8R,9S,10S,13R,14S,17R)-10,13-dimethyl-3,7,12-trioxohexadecahydro-1H-cyclopenta[a]phenanthren-17-yl)pentanoyloxy)-1,1,2,2-tetrafluorobutane-1-sulfonate (2.13 g, 3.37 mmol) were dissolved in dichloromethane (50 mL) and water (50 mL) and stirred at room temperature overnight. The dichloromethane layer was separated and the aqueous phase washed with dichloromethane (3×50 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 (2.77 g, 79%) as a white solid. 1H NMR (500 MHz, (CD3)2CO) δ: 8.53 (d, J=8 Hz, 2H), 8.35 (d, J=8 Hz, 2H), 8.04 (t, J=7.5 Hz, 2H), 7.83 (t, J=7.5 Hz, 2H), 7.50 (s, 2H), 7.40 (d, J=8 Hz, 2H), 7.31 (t, J=8 Hz, 2H), 7.24 (t, J=8 Hz, 1H), 4.65 (s, 2H), 4.32 (t, J=6.5 Hz, 2H), 3.05-3.17 (m, 2H), 2.94 (t, J=12.5 Hz, 1H), 2.64-2.82 (m, 5H), 2.21-2.53 (m, 12H), 1.72-2.10 (m, 17H), 1.56-1.65 (m, 1H), 1.47 (s, 3H), 1.28-1.38 (m, 5H), 1.10 (s, 3H), 0.83-0.87 (m, 3H).
