Abstract
A procedure for preparing a purine compound of the formula: **(See formula)** where R1 is hydrogen, halogen, hydroxyl, mercapto, lower alkoxy, lower aralkoxy or lower alcohol-uncle amino, lower alcohol amino, dialkoyl lower amino, aralkoyl lower amino, acylamino or hydroxyamino, R2 and R3 are each hydrogen, halogen, hydroxyl, mercapto, amino, lower alcohol, aryl, lower alkoxy, lower aralkoxy or lower alcohol-uncle, R4 is lower alcoholic, preferably with 2 to 6 carbon atoms, substituted with one or more hydroxyls (but no hydroxyl group being present at the carbon atom adjacent to the ring nitrogen atom), which may be protected with acyl, lower alcohol or lower aralkohyl, or, when there is a pair of hydroxyls in the alcohol group, with lower alcohol or lower aralkoxyl, and R is amino, lower amino alcohol or dialkoyl lower amino, and their salts, comprising reacting a purine compound of the formula: **(See formula)** wherein R'1 is hydrogen, halogen, hydroxyl, mercapto, lower alkoxy, lower aralkoxy, lower alcohol-uncle, amino, lower alcohol amino, dialcoyl lower amino, lower aralkoxy amino, acylamino or hydroxyamino, R'2 and R' 3 are each hydrogen, halogen, hydroxyl, mercapto, amino, lower alcohol, aryl, lower alkoxy, lower aralkoxy or lower alcohol-uncle and R'4 is lower alcoholic, preferably with 2 to 6 carbon atoms, substituted with one or more hydroxyls (but no hydroxyl group being present on the carbon atom adjacent to the ring nitrogen atom), which may be protected with acyl, lower alcohol or lower aralkohyl, or, when a pair of hydroxyl exists in the alcohol group, with lower alcoholylidene or lower aralkoxylidene, or its functional derivative on the carboxyl group with an amine of formula RH, where R is as defined above, and, if desired, converting the resulting compound to its salt according with the conventional method.
