Versuchsvorschrift

Phenylsulfonylchloride (57 mg, 0.33 mmol) was added to a stirred solution of (2R,3R,4S,5R)-2-[2-(aminomethyl)-6-(phenethylamino)-9H-purin-9-yl]-5-(methoxymethyl)tetrahydro-3,4-furandiol (150 mg, 0.36 mmol) (preparation 48) and triethylamine (110 mg, 1.08 mmol) in tetrahydrofuran (24 ml). The reaction mixture was stirred for 30 min at room temperature and then the solvent was removed under reduced pressure. The residue was azeotroped with dichloromethane and then purified by column chromatography on silica gel eluting with a solvent system of dichloromethane:methanol (95:5) to give the title compound (180 mg) as a foam. MS: 577 (MNa+).
