Procedure
1-(6-Amino-9H-purin-9-yl)-1,3-dideoxy-3-[N-tert-butoxycarbonyl-O-(2,6-dichlorobenzyl)-L-tyrosylamino]-β-D-ribofuranuronic acid (260 mg) was prepared by reacting 1-(6-amino-9H-purin-9-yl)-1,3-dideoxy-3-amino-β-D-ribofuranuronic acid monohydrate (223.5 mg) prepared in Example 99 with N-hydroxysuccinimide ester of N-tert-butoxycarbonyl-O-(2,6-dichlorobenzyl)-L-tyrosine (388 mg) according to a similar manner to that of Example 5, mp. 166°-176° C. (dec.).
