Reaction Steps

The title compound was prepared by a similar method to example 6 using (2R,3R,4S,5R)-2-{2-(aminomethyl)-6-[(2,2-diphenylethyl)amino}-9H-purin-9-yl}-5-(methoxymethyl)tetrahydro-3,4-furandiol (400 mg, 0.78 mmol) (example 1), sodium triacetoxyborohydride (260 mg, 1.23 mmol), 4-methoxycyclohexanone (100 mg, 0.78 mmol) (J. Am. Chem. Soc. 5190, 89, 1967) and acetic acid (56 mg, 0.93 mmol) in tetrahydrofuran (30 ml). The product was purified by column chromatography on silica gel eluting with a solvent system of dichloromethane:methanol:ammonia (94:6:0.3) to give the title compound as a mixture (3:2 ratio) of diastereoisomers (118 mg) as a foam. MS: 603 (MH+).
