Versuchsvorschrift

A mixture of 4-((1R,3aS,5aR,5bR,7aR,11aS,11bR,13aR,13bR)-3a-((2-(1,1-dioxido-4-thiomorpholinyl)ethyl)amino)-1-isopropenyl-5a,5b,8,8,11a-pentamethyl-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)benzoyl chloride (30 mg, 0.042 mmol), cyclopropanesulfonamide (6.15 mg, 0.051 mmol), Hunig's Base (0.022 mL, 0.127 mmol) and DMAP (2.58 mg, 0.021 mmol) in dichloromethane (1 mL) was stirred for 16 h at room temperature. The crude reaction mixture was purified by prep HPLC to provide the title compound as a white solid (4 mg, 11%).
