Procedimiento

A mixture of methyl 4-((1R,3aS,5aR,5bR,7aR,11aS,11bR,13aR,13bR)-3a-((3-(1,1-dioxido-4-thiomorpholinyl)propyl)amino)-1-isopropenyl-5a,5b,8,8,11a-pentamethyl-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 (15 mg, 0.021 mmol) and 1N sodium hydroxide (0.104 mL, 0.104 mmol) in dioxane (1 mL) was heated at 78° C. for 3 hours. The reaction mixture was purified by prep HPLC to provide the title compound as a white solid (9 mg, 58%).
