Reaction Steps

To a solution of Compound 20 (0.354 g, 0.565 mmol) in methanol (14 ml), triethylamine (3.3 ml) was added, and the mixture was stirred for one day at room temperature under air-tight condition. The mixture was concentrated under reduced pressure. The residue was applied to a silica gel column (10 g, eluent; ethyl acetate:n-hexane:ethanol 20:10:1), to thereby yield Compound 21 in an amount of 0.283 g (86%).
