Procedure

The title compound was prepared following the method described above for the synthesis of 4-((1R,3aS,5aR,5bR,7aR,11aS,11bR,13aR,13bR)-5a,5b,8,8,11a-pentamethyl-3a-((2-(methylsulfonamido)ethyl)amino)-1-(prop-1-en-2-yl)-2,3,3a,4,5,5a,5b,6,7,7a,8,11,11a,11b,12,13,13a,13b-octadecahydro-1H-cyclopenta[a]chrysen-9-yl)benzoic acid using cyclopropanesulfonyl chloride as the reagent in Step 1. The product was isolated as a colorless oil (3.5 mg, 34%). LCMS: m/e 677.52 (M+H)+, 2.32 min (method 11). 1H NMR (400 MHz, CHLOROFORM-d) δ 9.55 (br. s., 1H), 7.98 (d, J=8.3 Hz, 2H), 7.23 (d, J=8.3 Hz, 2H), 6.76 (br. s., 1H), 5.99 (br. s., 1H), 5.21 (d, J=5.0 Hz, 1H), 4.85 (s, 1H), 4.71 (s, 1H), 3.92-3.71 (m, 1H), 3.69-3.55 (m, 1H), 3.23 (br. s., 2H), 2.91-2.70 (m, 1H), 2.63-2.44 (m, 1H), 2.25-1.02 (m, 26H), 1.70 (s, 3H), 1.18 (s, 3H), 1.02 (s, 3H), 0.97 (s, 3H), 0.92 (s, 3H), 0.92 (s, 3H).
