Reaction Steps

Sodium (67 mg, 2.90 mmol) was dissolved in 2-mercapt ethanol (2.5 ml) and thereto was added 2-chloro-8-hydroxy-9-(3-methoxycarbonylmethylbenzyl)adenine (100 mg, 0.29 mmol) obtained by Example 98. The mixture was stirred at 120° C. for 4 hours and then neutralized with 12N hydrochloric acid. After removing the solvent, to the residue were added methanol (3.0 ml) and concentrated sulfuric acid (0.14 g, 1.43 mmol), and the mixture was refluxed for 30 minutes. The solution was neutralized with saturated sodium hydrogencarbonate solution and extracted with chloroform. The organic layer was dried over anhydrous magnesium sulfate and concentrated. To the residue was added water, the mixture was filtered and washed with water to give the captioned compound (55 mg, 0.14 mmol, yield: 49%) as a white solid.
