N-[(1S,2R,3S,4R)-4-(2,6-Dichloro-purin-9-yl)-2,3-dihydroxy-cyclopentyl]-propionamide (160) mg, 0.44 mmol) is dissolved in THF (5 ml) under an atmosphere of argon. Diisopropylamine (69 mg, 0.53 mmol) is added followed by 2,2-diphenylethylamine (96 mg, 0.49 mmol) and the reaction mixture is stirred at 50° C. The reaction is shown to be complete by LCMS after 2 hours. The solvent is removed in vacuo and the title compound is obtained after purification by reverse phase column chromatography (Isolute™ C18, 0-100% acetonitrile in water—0.1% TFA).). 1H nmr (MeOD, 400 MHz); 8.00(s, 1H), 7.40-7.15(m, 10H), 4.75(m, 1H), 4.60(m, 1H), 4.50(m, 1H), 4.20(m, 3H), 3.95(m, 1H), 2.85(m, 1H), 2.40(q, 2H), 2.10(m, 1H), 1.20(t, 3H), MS (ES+) m/e 521 (MH+).
