Procedure

The title compound was prepared by a similar method to example 6 from (2R,3R,4S,5R)-2-{2-(aminomethyl)-6-[(2,2-diphenylethyl)amino]-9H-purin-9-yl}-5-(methoxymethyl)tetrahydro-3,4-furandiol (example 1) (110 mg, 0.22 mmol), cyclopentanone (18 mg, 0.21 mmol), sodium triacetoxyborohydride (70 mg, 0.33 mmol) and acetic acid (0.14 ml, 0.25 mmol) to afford the title compound as a solid (48 mg). MS: 559 (MH+).
