실험 절차

(2R,3R,4R,5R)-4-acetyloxy-5-(acetyloxymethyl)-2-(6-chloro-2-iodopurin-9-yl)oxolan-3-yl acetate (3.71 mmol) in dry tetrahydrofuran (60ml) was mixed with O-methyl hydroxylamine hydrochloride (37.1 mmol) and triethylamine (6.2 mL). The mixture was stirred at room temperature for 96 hours under an atmosphere of nitrogen. The solvent was removed in vacuo and the residue chromatographed on a flash silica gel column eluting with CHCl3—CH3OH (99:1), to give (2R,3R,4R,5R)-4-acetyloxy-5-(acetyloxymethyl)-2-[2-iodo-6-(methoxyamino)purin-9-yl]oxolan-3-yl acetate, a compound of formula (4), which was crystallized from a mixture of chloroform/hexanes (1:1).
