実験手順

To a solution of (1S,4S)-tert-butyl 5-(2-(((1R,3aS,5aR,5bR,7aR,11aS,11bR,13aR,13bR)-9-(4-(methoxycarbonyl)phenyl)-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-3a-yl)amino)ethyl)-2,5-diazabicyclo[2.2.1]heptane-2-carboxylate (419 mg, 0.545 mmol) in DCM (10 mL) was added TFA (2 mL, 26.0 mmol) and the mixture was stirred at rt for 3 h. The reaction mixture was concentrated and dark brown viscous oil was dried to remove all TFA. The material was purified by reverse phase HPLC using HPLC method 6 and dried under vacuum to give methyl 4-((1R,3aS,5aR,5bR,7aR,11aS,11bR,13aR,13bR)-3a-((2-((1S,4S)-2,5-diazabicyclo[2.2.1]heptan-2-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, 3 TFA (75.2 mg, 12.28% yield) as a light brown solid.
