Product 1
Procedure
The title compound was prepared following the method described in Example B2 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)piperazine (prepared as described below) as the alkylating reagent in Step 3. The product was isolated as a white solid (11 mg, 56%). LCMS: m/e 724.6 (M+H)+, 2.44 min (method 10). 1H NMR (500 MHz, Acetic) δ 8.02 (d, J=8.2 Hz, 2H), 7.36 (d, J=8.2 Hz, 2H), 3.63-3.29 (m, 7H), 3.25-3.14 (m, 1H), 3.13-2.99 (m, 4H), 2.93 (s, 3H), 2.50 (dd, J=13.0, 2.6 Hz, 1H), 2.32-0.98 (m, 26H), 1.25 (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).
