The title compound was prepared by a similar method to example 3 using (2R,3R,4S,5R)-2-{2-(aminomethyl)-6-[(2,2-diphenylethyl)amino}-9H-purin-9-yl}-5-(methoxymethyl)tetrahydro-3,4-furandiol (example 1) (245 mg, 0.48 mmol), tetrahydro-2H-pyran-4-ylmethanesulfonyl chloride (preparation 21) (95 mg, 0.48 mmol), triethylamine (145 mg, 1.44 mmol) in tetrahydrofuran (23 ml). Purification by column chromatography on silica gel eluting with a solvent system of dichloromethane:methanol:ammonia (95:5:0.25) gave the title compound as an oil (118 mg). MS: 654 (MH+).
