Process for producing N6,O2'-diacyladenosine-3',5'-cyclic phosphoric ester alkali metal salts

摘要

An N6,O2'-diacyladenosine-3',5'-cyclic phosphoric ester alkali metal salt can be obtained with ease and in a high yield by reacting an adenosine-3',5'-cyclic phosphoric ester alkali metal salt with a carboxylic anhydride having 4 or less carbon atoms at a temperature of 70 DEG C. or above.
