Deprotection was performed (room temperature, 2 hours) by using Intermediate 84 (81.9 mg) and a mixed solution of trifluoroacetic acid and methylene chloride (1:1, 2 ml). The solvent was evaporated under reduced pressure, and the residue was added with methanol (2 ml) and diethyl ether (6 ml). The deposited precipitates were collected by filtration and washed with diethyl ether to obtain the title compound (64 mg) as yellow powdery crystals.
