実験手順

A mixture of methyl 4-((1R,3aS,5aR,5bR,7aR,11aS,11bR,13aR,13bR)-3a-(2-aminoethylcarbamoyl)-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 (20 mg, 0.033 mmol) and methyl acrylate (8.40 mg, 0.098 mmol) in methanol (1 mL) was stirred at 20° C. for 3 hours. LCMS indicated the mono-substitution. Methyl acrylate (8.40 mg, 0.098 mmol) was added to the reaction mixture again. The reaction mixture was stirred for 16 hours. The reaction mixture was quenched with distilled water, extracted with DCM (3×3 mL). All the extracts were combined, dried over sodium sulfate, filtered and concentrated under reduced pressure to provide the title compound as a white solid (25 mg, 98%). LCMS: m/e 787.48 (M+H)+, 2.67 min (method 1).
