The title compound was prepared following the method described 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 4-(2-chloroethyl)morpholine as the alkylating reagent in Step 3. The product was isolated as a colorless oil (4 mg, 39%). LCMS: m/e 647.58 (M+H)+, 2.35 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), 3.94 (d, J=3.7 Hz, 4H), 3.73-3.44 (m, 4H), 3.27 (br. s., 4H), 2.50 (d, J=10.4 Hz, 1H), 2.32-1.01 (m, 26H), 1.21 (s, 3H), 1.12 (s, 3H), 1.08 (s, 3H), 0.93 (d, J=6.7 Hz, 3H), 0.86 (d, J=6.7 Hz, 3H), 0.83 (s, 3H), 0.79 (s, 3H).
