Procedimiento

5-(4-(2-(1-ethylcyclopentyloxy)-2-oxoethoxy)-3,5-dimethylphenyl)-5H-dibenzo[b,d]thiophenium bromide (4.20 g, 7.79 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 (4.78 g, 7.56 mmol) were dissolved in dichloromethane (225 mL) and water (225 mL) and stirred at room temperature overnight. The dichloromethane layer was separated and the aqueous phase washed with dichloromethane (3×250 mL). The combined organic layers were washed with water (4×250 mL), concentrated in vacuo and residual water removed via azeotrope with acetonitrile (2×250 mL) to afford the title compound (6.48 g, 80%) as a white solid. 1H NMR (500 MHz, (CD3)2CO) δ: 8.53 (d, J=8 Hz, 2H), 8.37 (d, J=8 Hz, 2H), 8.04 (t, J=7.5 Hz, 2H), 7.85 (t, J=7.5 Hz, 2H), 7.52 (s, 2H), 4.57 (s, 2H), 4.32 (t, J=7 Hz, 2H), 3.06-3.17 (m, 3H), 2.95 (t, J=12.5 Hz, 1H), 2.66-2.83 (m, 3H), 2.2-2.54 (m, 8H), 1.57-2.14 (m, 13H), 1.48 (s, 3H), 1.25-1.41 (m, 7H), 1.90-1.12 (m, 6H), 0.82-0.89 (m, 9H).
