Vorschrift

According to the method of Example 1, Step C, deprotection was performed (room temperature, 31 hours) by using Intermediate 39 (214 mg) and 10% hydrogen chloride/methanol solution (5 ml). The solvent was evaporated under reduced pressure, and the residue was added with methanol (1 ml) and diethyl ether (3 ml). The deposited precipitates were collected by filtration and washed with diethyl ether to obtain the title compound (215 mg) as light yellow powdery solid.
