실험 절차

A mixture 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) (0.35 g, 0.64 mmol) and 1,3-diaminopropane (0.45 g, 6.1 mmol) was heated at 100° C. for 3 hours. The mixture was dissolved in a little dichloromethane and purified by column chromatography on silica gel eluting with a gradient system of dichloromethane:methanol:concentrated aqueous ammonia (80:20:1.2, by volume) changing to dichloromethane methanol:concentrated aqueous ammonia (88:12:2, by volume). After evaporation of appropriate fractions the residue was triturated with diethyl ether, filtered and dried to yield the target compound as a white solid, (0.22 g, 58%).
