실험 절차

To a solution of tert-butyl 4-((1R,3aS,5aR,5bR,7aR,11aS,11bR,13aR,13bR)-3a-formyl-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 (0.1 g, 0.167 mmol) in DCE (2 ml) was added acetic acid (0.019 ml, 0.334 mmol) and (2-Amino-1-(3-pyridyl)ethyl)dimethylamine (0.055 g, 0.334 mmol). The mixture was stirred at rt for 2 h then sodium triacetoxyborohydride (0.177 g, 0.835 mmol) was added and it was stirred at rt for three days. The mixture was diluted with 7 ml of sat. NaHCO3 and was extracted with dichloromethane (3×7 ml). The combined organic layers were dried with Na2SO4. The drying agent was removed by filtration and the filtrate was concentrated under reduced pressure. The crude product was used in the next step with no additional purification. LCMS: m/e 748.3 (M+H)+, 3.47 min (method 6).
