Conclusions

  1. 1.

    The reaction of 2,6-diamino-4-hydroxy-5-formamidopyrimidine with pyruvaldehyde gives a mixture of the 6- and 7-methylpterins in a 1∶3 ratio.

     
  2. 2.

    The condensation of 2-amino-4-hydroxy-5-phenylazo-6-chloropyrimidine with the ethylene ketal of aminoacetone, followed by reduction of the phenylazo group, hydrolysis, and cyclization leads to the formation of 6-methyl-7,8-dihydropterin.

     
  3. 3.

    The oxidation of 6-methylpterin with SeO2 in AcOH in the presence of NiCl2 gives 6-formylpterin.
