Versuchsvorschrift
A stirred suspension of 15.0 g (103 mmol) of 1 in 250 mL water was added 12 g (375 mmol) of anhydrous hydrazine, and the mixture was heated at reflux for 3 h. The resulting clear solution was cooled, and the precipitate which separated was collected by filtration, washed with water followed by ethanol and dried to give 6.6 g (46%) of white solid. mp decomposes at 313° C. (Literature mp 314-315° C., see Taylor, E. C.; Cocuzza, J. A. Synthesis and Properties of 7-Azaxanthopterin. J. Org. Chem. 1979, 44, 1125-1128).
