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), phenylsulfonyl chloride (70 mg, 0.40 mmol) and triethylamine (0.15 ml, 1.08 mmol). The compound was purified by column chromatography on silica gel eluting with a solvent system of dichloromethane:methanol (95:5) to give the title compound (145 mg) as a powder. MS: 645 (MH+).
