Procedure

A mixture of 2,6-Diamino-9-(2'-O-propyl-β-D-ribofuranosyl)purine and 2,6-Diamino-9-(3'-O-propyl-β-D-ribofuranosyl)purine (4.6 gm) and adenosine deaminase (200 mg, Sigma Chemicals Type II) were stirred at room temperature overnight in 0.1 M tris buffer (150 ml, pH 7.4), DMSO (100 ml) and 0.1 M sodium phosphate buffer (10 ml). A further aliquot of adenosine deaminase (140 mg) in 0.1 M phosphate buffer (30 ml) and DMSO (20 ml) was added and the reaction stirred an addition 24 hrs. The solvent was evaporated in vacuo and the residue flash chromatographed on silica gel utilizing 5→20% MeOH/CH2Cl2. Product-containing fractions were evaporated in vacuo and the residue crystallized from H2O to yield 2.6 gm of product. m.p. dec >270° C. 1H NMR (DMSO-d6) δ 0.75 (t, 3, CH3), 1.42 (tq, 2, CH2), 3.3-3.6 (m, 4, H-5', O-CH2), 3,85 (m, 1), 4.2 (m, 1), 4.23 (m, 1), 5.10 (t, 1, 5'-OH), 5.13 (d, 1, 3'-OH), 5.75 (d, 1, H-1') , 6.45 (br s, 2, NH2), 7.95 (s, 1, H-8) and 10.67 (br s, 1, NH).
