実験手順

A suspension of 1-(6-benzoylamino-9H-purin-9-yl)-3-(N-benzyloxycarbonyl-O-methyl-L-tyrosylamino)-1,3-dideoxy-β-D-ribofuranuronic acid (300 mg) prepared in Example 2 in a mixture of methanol (20 ml) and n-butylamine (10 ml) was boiled under reflux for 1 hour. The mixture was evaporated under reduced pressure. The residue was subjected to column chromatography on silica gel and eluted with a mixture of chloroform and methanol (7:3). The fractions containing the object compound were combined and the solvent was evaporated to give 1-(6-amino-9H-purin-9-yl)-3-(N-benzyloxycarbonyl-O-methyl-L-tyrosylamino)-1,3-dideoxy-β-D-ribofuranuronic acid (200 mg).
