Procedure

2-Butoxy-8-hydroxy-9-{3-(2-benzyloxyethoxycarbonyl)benzyl}adenine (0.03 g, 0.06 mmol) obtained by Example 5, 5% Pd/C (60 mg) and concentrated hydrochloric acid (0.1 ml) were added to a mixed solvent of THF (30 ml) and methanol (30 ml), and the mixture was stirred under hydrogen atmosphere at room temperature for 60 hours. The reaction mixture was filtered, neutralized with saturated sodium hydrogencarbonate solution and extracted with dichloromethane. The organic layer was dried over anhydrous magnesium sulfate and concentrated. The residue was purified by column chromatography (SiO2 20 g, eluting solvent: CHCl3/MeOH=100/1˜50/1) and washed with methanol to give the captioned compound (0.01 g, 0.02 mmol, yield: 42%) as a white solid.
