Heterocyclic Compounds from 3,4-Diaminodimethylamino-1-methylpyrazolo[3,4-d]pyrimidine: Approach to Novel ortho- and peri-Fused Heterocyclic Ring System
Syntheses of New Pyrazolo[3,4-d]-pyrimidine Derivatives Starting from 1,1-Diamino-2,2-dicyanoethylene
摘要:
3,4-Diamino-6-dimethylamino-1-methylpyrazolo[3,4-6]-pyrimidine (4) was prepared from the reaction of 6-amino-4-chloro-5-cyano-2-dimethylaminopyrimidine (3) with methylhydrazine. It reacted further with different aldehydes giving a variety of new pyrazolo[3,4-d]-pyrimidine derivatives.
