Reaction Steps

(2R,3R,4S,5R)-2-{2-(Aminomethyl)-6-[(2,2-diphenylethyl)amino]-9H-purin-9-yl}-5-(methoxymethyl)tetrahydro-3,4-furandiol (example 1) (300 mg, 0.61 mmol) was dissolved in dry tetrahydrofuran (20 ml) (using gentle heating), a solution of 2-methyl-1-propanesulphonyl chloride (50 mg, 0.32 mmol) in dry tetrahydrofuran (2.5 ml) added and the mixture stirred at room temperature for 18 hr under a nitrogen atmosphere. A solution of triethylamine (100 mg, 0.98 mmol) and 2-methyl-1-propanesulphonyl chloride (50 mg, 0.32 mmol) in dry tetrahydrofuran (5 ml) was added and the resulting mixture stirred for a further 5 hr. The solvent was then removed under reduced pressure and the residue purified by column chromatography on silica gel eluting with a solvent system of dichloromethane:methanol (97:3), to give the product as a foam (117 mg). MS: 611 (MH+).
