Versuchsvorschrift

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) (1.1 g, 2 mmol) and 1,2-ethylenediamine (1.1 g, 18.3 mmol) was heated at 105° C. for 2.5 hours. The mixture was dissolved in a little dichloromethane and purified by column chromatography on silica gel eluting with dichloromethane:methanol:concentrated aqueous ammonia (85:15:1.5, 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, (0.99 g, 86%).
