Procedure

The title compound was prepared by a similar method to example 3 using (2R,3R,4S,5R)-2-{2-(2-aminoethyl)-6-[(2,2-diphenylethyl)amino]-9H-purin-9-yl}-5-(methoxymethyl)tetrahydro-3,4-furandiol (example 11) (200 mg, 0.40 mmol), benzenesulphonyl chloride (70 mg, 0.40 mmol) and triethylamine (0.15 ml, 1.08 mmol) to afford the title compound as a solid (145 mg). MS: 645 (MH+).
