Vorschrift

A mixture of methyl 4-((1S,3aS,5aR,5bR,7aS,9S,11aS,11bR,13aR,13bR)-3a-((2-(1,1-dioxidothiomorpholino)ethyl)amino)-1-isopropyl-5a,5b,8,8,11a-pentamethylicosahydro-1H-cyclopenta[a]chrysen-9-yl)benzoate (40 mg, 0.056 mmol) and sodium hydroxide (0.564 mL, 0.564 mmol) in dioxane (1 mL) was heated up at 80° C. for 3 hours. The reaction mixture was filtered and purified by HPLC to provide the title compound as white solid (30 mg, 73%). LCMS: m/e 695.46 (M+H)+, 2.55 min (method 10). 1H NMR (500 MHz, Acetic) δ 8.02 (d, J=8.5 Hz, 2H), 7.36 (d, J=8.5 Hz, 2H), 3.44-3.36 (m, 1H), 3.35-3.21 (m, 6H), 3.19-2.99 (m, 5H), 2.50 (dd, J=13.0, 2.9 Hz, 1H), 2.34-1.01 (m, 26H), 1.28 (s, 3H), 1.13 (s, 3H), 1.10 (s, 3H), 0.93 (d, J=6.7 Hz, 3H), 0.85 (d, J=6.7 Hz, 3H), 0.84 (s, 3H), 0.80 (s, 3H).
