Versuchsvorschrift

To a solution of methyl 4-((1R,3aS,5aR,5bR,7aR,11aS,11bR,13aR,13bR)-3a-(2-(tert-butoxycarbonylamino)ethylamino)-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 (900 mg, 1.310 mmol) in dioxane (1 mL) was added HCl (4M in dioxane) (4.26 mL, 17.03 mmol) and the reaction mixture was stirred for 4 h at rt. The reaction mixture was concentrated under reduced pressure to provide the title compound as a brown solid (769 mg, 100%). LCMS: m/e 588.08 (M+H)+, 2.44 min (method 11).
