実験手順
A solution of methyl 6-[(2,2-diphenylethyl)amino]-9-{(2R,3R,4S,5S)-5-[(ethylamino)carbonyl]-3,4-dihydroxytetrahydro-2-furanyl}-9H-purine-2-carboxylate (Preparation 9) (0.7 g, 1.28 mmol) and 10% w/w aqueous sodium hydroxide solution (1.3 ml, 3.2 mmol) in methanol (2.3 ml) was stirred at room temperature for 14 hours. The solution was adjusted to pH 4 by the addition of 2N aqueous hydrochloric acid and the precipitated white solid collected by filtration. The solid was washed with water and dried under reduced pressure to give the target compound as a white powder, (0.21 g, 30%).
