Taylor, Edward C. published the artcilePteridines. XXXI. New and unequivocal synthesis of isoxanthopterin-6-carboxylic acid (Cyprino-Pourpre B), SDS of cas: 5098-14-6, the publication is Tetrahedron Letters (1973), 2093-5, database is CAplus.

Condensation of HC(CN)2NH2 with HON:CHCOCH:NOH gave 2-amino-3-cyano-5-oximinomethylpyrazine 1-oxide which cyclized with guanidine to the pteridine oxide (I). Heating I in POCl3-DMF gave the chloronitrile (II) which under reflux in aqueous NaOH gave isoxanthopterin-6-carboxylic acid (III).
