Versuchsvorschrift

To a cloudy mixture of methyl 4-((1R,3aS,5aR,5bR,7aR,11aS,11bR,13aR,13bR)-3a-(cyclopropylmethylamino)-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 (0.024 g, 0.040 mmol) in 1,4-dioxane (1.5 mL) was added NaOH (1N) (0.5 mL, 0.5 mmol). The mixture was heated to 65° C. After two hours, the mixture was cooled to rt and stirred at rt overnight. The mixture was filtered through plug of glass wool and was purified by prep HPLC to afford the title compound (0.007 g, 10.79 μmol, 26.9% yield) as a white film. LCMS: m/e 584.6 (M+H)+, 1.83 min (method 2). 1H NMR (400 MHz, CHLOROFORM-d) δ ppm 8.00 (2H, d, J=8.0 Hz), 7.21 (2H, d, J=8.0 Hz), 5.31 (1H, d, J=5.0 Hz), 4.75 (1H, d, J=1.5 Hz), 4.61 (1H, s), 2.76 (1H, td, J=10.9, 5.6 Hz), 2.62 (1H, dd, J=11.2, 6.1 Hz), 2.23 (1H, dd, J=11.5, 7.8 Hz), 1.97-2.16 (3H, m), 1.82-1.95 (2H, m), 1.70 (3H, s), 1.16 (3H, s), 1.01 (3H, s), 1.00 (3H, s), 0.96 (3H, s), 0.95 (3H, s), 0.80-1.77 (19H, m), 0.48-0.58 (2H, m), 0.09-0.24 (2H, m).
