実験手順

To a suspension of 1-(6-benzoylamino-9H-purin-9-yl)-1,3-dideoxy-3-(N-benzyloxycarbonyl-O-methyl-L-tyrosylamino)-β-D-ribofuranuronic acid (695 mg) prepared in Example 2 in ethyl acetate (200 ml) was added excess ethereal solution of diazomethane and the mixture was stirred for 30 minutes at room temperature. The resulting solution was evaporated to dryness and the residue was triturated in diethyl ether to give methyl 1-(6-benzoylamino-9H-purin-9-yl)-1,3-dideoxy-3-(N-benzyloxycarbonyl-O-methyl-L-tyrosylamino)-β-D-ribofuranuronate (700 mg), mp. 124°-128° C. (dec.).
