Abstract

A method of preparing pteridine derivatives of formula (I) or one of its tautomeric forms or one of its salts. **(See formula)** wherein R1 and R2 are the same or different and each is a lower alcohol group or R1 and R2, together with the carbon atom in the pteridine ring structure, forms a spirocycloalkoxy ring system having 4 to 6 carbon atoms outside the pteridine ring structure, characterized by selective oxidation of a compound of formula (II), **(See formula)** where R1 and R2 are as defined above.
