Vorschrift

The title compound was prepared following the method described in above for the synthesis of 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)benzoic acid using 1-(2-chloroethyl)-4-(methylsulfonyl)piperidine (prepared as described below) as the alkylating reagent in Step 3. The product was isolated as a white solid (24 mg, 36%). LCMS: m/e 723.56 (M+H)+, 2.28 min (method 11). 1H NMR (500 MHz, Acetic) δ 8.02 (d, J=8.2 Hz, 2H), 7.36 (d, J=8.2 Hz, 2H), 3.77-3.63 (m, 2H), 3.62-3.54 (m, 3H), 3.50 (d, J=5.5 Hz, 1H), 3.35 (td, J=11.4, 3.7 Hz, 1H), 3.08-2.89 (m, 2H), 3.02 (s, 3H), 2.50 (d, J=13.1 Hz, 1H), 2.42-2.29 (m, 2H), 2.28-1.03 (m, 28H), 1.21 (s, 3H), 1.12 (s, 3H), 1.08 (s, 3H), 1.01 (d, J=11.3 Hz, 1H), 0.93 (d, J=6.7 Hz, 4H), 0.86 (d, J=6.7 Hz, 4H), 0.83 (s, 3H), 0.79 (s, 3H).
