Sodium methoxide (40 mg, 0.74 mmole) was added to a solution of 9-[(1R,2R,4S,5S)-4,5-bis(benzoyloxymethyl)-2-hydroxycyclohexyl]-adenine (185 mg, 0.37 mmole) in a solvent mixture consisting of anhydrous methanol (4 ml) and anhydrous THF (4 ml) under ice cooling. After stirring the resulting mixture at room temperature for 5 hours, the reaction mixture was neutralized with dilute hydrochloric acid, and the solvent was distilled off therefrom under reduced pressure. The residue was purified by Diaion HP-20 column chromatography (methanol concentration gradient) to obtain 9-[(1R,2R,4S,5S)-4,5-bis(hydroxymethyl)-2-hydroxycyclohexyl]-adenine (109 mg, Yield 100%).
