実験手順

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) (1.0 g, 1.83 mmol) and 1-benzyl-4-piperidinylamine (2.4 ml, 11 mmol) was heated at 105 ° C. for 4 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 (98:2, by volume) changing to dichloromethane:methanol (95:5, 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, (1.0 g, 80%).
