Procedure

A mixture of methyl 4-((1R,3aS,5aR,5bR,7aR,11aS,11bR,13aR,13bR)-3a-((2-(4-(cyclopropylsulfonyl)piperazin-1-yl)ethyl)amino)-5a,5b,8,8,11a-pentamethyl-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)benzoate (30 mg, 0.039 mmol) and sodium hydroxide (0.395 mL, 0.395 mmol) in dioxane (0.5 mL) was heated up at 80° C. for 3 hours. The reaction mixture was filtered and the clear solution was purified by HPLC to provide the title compound as a white solid (13 mg, 42%).
