Reaction Steps

The title compound was prepared following steps 5 and 6 using methyl 2-fluoro-4-((1R,3aS,5aR,5bR,7aR,11aS,11bR,13aR,13bR)-3a-formyl-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 and 4-(3-aminopropyl) thiomorpholine 1,1-dioxide as the reactant amine. The product was isolated as a white solid (50 mg, 55.0%).
