Procedure

The compound (90 mg, 74.6 μmol) synthesized in Example 12 (12a) was dissolved in methanol (10 mL) and hydrochloric acid (140 μL) and 20% palladium hydroxide-carbon (90 mg) were added thereto, followed by stirring of the mixture at room temperature under a hydrogen atmosphere for 2 hours. After the celite filtration, ammonia water (5%) was added thereto until the pH became neutral. The solvent was distilled off under reduced pressure and the residue was purified by ion exchange resin (Dowex 50w×8) column (water-5% ammonia water). Further, it was purified using silica gel flash column chromatography (ethyl acetate:methanol:water, 1:1:1, V/V) to obtain the desired title compound (26 mg, 79%) as a colorless solid.
