Abstract

Process for the preparation of 4-hydroxy-pyrazolo- (3,4-d) -pyrimidine of the formula ** (see formula) ** Or of its salts or chelates with physiologically compatible agents, characterized in that a 4-hydroxy-6-halogen-pyrazolo- (3,4-d) -pyrimidine solution of the formula is subjected to dehalogenation ** (see formula) ** Wherein x represents a halogen atom, by treatment with nascent and/or catalytically activated hydrogen, and the product obtained is optionally converted into a salt or chelate.
