A mixture of 1-(6-amino-9H-purin-9-yl)-1,3-dideoxy-3-(O-methyl-L-tyrosylamino)-β-D-ribofuranuronic acid dihydrochloride monohydrate (5.48 g) prepared in Example 98 in 1N methanolic sodium hydroxide solution (1000 ml) was heated under reflux for 20 hours. The reaction mixture was evaporated and the residue was neutralized with concentrated hydrochloric acid. The aqueous solution was subjected to column chromatography on a non-ionic adsorption resin "HP-20" (trade mark, Mitsubishi Chemical Industries Ltd.) (500 ml). The elution was carried out with water, and the eluate was concentrated, stood overnight. The resulting precipitates were collected, washed with water, and dried to give 1-(6-amino-9H-purin-9-yl)-1,3-dideoxy-3-amino-β-D-ribofuranuronic acid monohydrate (2.47 g).
