실험 절차
(1S,2R,3S,5R)-3-Amino-5-[2-chloro-6-(2,2-diphenyl-ethylamino)-purin-9-yl]-cyclopentane-1,2-diol trifluoroacetate (9.50 g, 16.42 mmol) and diisopropylethylamine (6.36 g, 49.27 mmol) are placed in a flask with dry THF (150 ml). Propionyl chloride (1.52 g, 16.42 mmol) is added dropwise and the reaction mixture is stirred at room temperature. The reaction is shown to be complete by LCMS after 1 hour. The solvent is removed in vacuo and the residue is partitioned between dichloromethane (250 ml) and water (250 ml). The organic layer is washed with water (200 ml) and brine (200 ml), dried over MgSO4, filtered and the solvent is removed in vacuo. The solid is recrystallised from 1,2-dichloroethane to give the title compound. 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+).
