실험 절차

To a flask containing a suspension of ethyl 4-((1R,3aS,5aR,5bR,7aR,11aS,11bR,13aR,13bR)-3a-(aziridin-1-yl)-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)cyclohex-3-enecarboxylate (0.202 g, 0.344 mmol) in 1,4-dioxane (3 mL) was added Hunig's base (0.421 mL, 2.408 mmol) followed by morpholine (0.150 mL, 1.720 mmol). The mixture was heated to 100° C. for 15.5 h then was cooled to rt. The mixture was directly purified by flash chromatography using a 0-40% ethyl acetate in hexanes gradient and a 25 g silica gel column. The fractions containing the expected product were combined and were concentrated under reduced pressure to give ethyl 4-((1R,3aS,5aR,5bR,7aR,11aS,11bR,13aR,13bR)-5a,5b,8,8,11a-pentamethyl-3a-((2-morpholinoethyl)amino)-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)cyclohex-3-enecarboxylate (0.148 g, 0.219 mmol, 63.7% yield) as a white foam. LCMS: m/e 675.8 (M+H)+, 2.06 min (method 1).
