A mixture of 4-((1R,3aS,5aR,5bR,7aR,11aS,11bR,13aR,13bR)-3a-(hydroxymethyl)-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)benzoic acid (50 mg, 0.092 mmol) and a catalytic amount of Pd/C (9.77 mg, 0.092 mmol) was dissolved in a mixture of methanol (1 mL) and ethyl acetate (1 mL) and stirred under 1 ATM of H2 for 24 hours. LCMS indicated the completion of the reaction. The reaction mixture was filtered to remove the catalyst. The solution was concentrated in vacuo and the residue was purified using reverse phase prep HPLC to afford the title compound as a white solid. LCMS: m/e 529.29 (M+H−H2O)+, 0.15 min (method 1). 1H NMR (500 MHz, CHLOROFORM-d) δ ppm 1H NMR (500 MHz, CHLOROFORM-d) δ ppm 0.80 (d, 3H), 0.88 (d, J=6.71 Hz, 3H), 0.97 (s, 6H), 1.02 (s, 6H), 1.12 (s, 3H), 1.18-2.23 (m, 24H), 3.36 (d, J=10.99 Hz, 1H), 3.84 (d, J=10.68 Hz, 1H), 5.27-5.42 (m, 1H), 7.26 (d, J=7.93 Hz, 2H), 8.01 (d, J=8.24 Hz, 2H).
