Participants

Reaction Steps

To a solution of (3S,5R,8R,9S,10S,13R,14S,17R)-14-hydroxy-10,13-dimethyl-17-(2-oxo-2H-pyran-5-yl)hexadecahydro-1H-cyclopenta[a]phenanthren-3-yl 4-nitrophenyl carbonate (29 mg, 0.054 mmol) in CH2Cl2 was added 2-morpholinoethanamine (70.2 mg, 0.54 mmol). The resultant mixture was stirred at rt for 16 h and then purified via preparative TLC to afford (3S,5R,8R,9S,10S,13R,14S,17R)-14-hydroxy-10,13-dimethyl-17-(2-oxo-2H-pyran-5-yl)hexadecahydro-1H-cyclopenta[a]phenanthren-3-yl (2-morpholinoethyl)carbamate (18 mg, 61.4%) as a white solid. LRMS (M+H+) m/z 543.4. 1H NMR (CD3OD, 400 MHz) δ 7.89 (dd, J=9.6, 2.4 Hz, 1H), 7.33 (m, 1H), 6.18 (d, J=9.6 Hz, 1H), 4.82 (m, 1H), 3.59 (m, 4H), 3.16 (m, 2H), 2.46 (m, 2H), 2.41 (m, 5H), 1.08-2.15 (m, 21H), 0.87 (s, 3H), 0.61 (s, 3H).
