Notes:
Condensation of 3-amino-4-carbethoxy-pyrazoles with nitriles led to a new synthesis of 6-C-substituted pyrazolo[3,4-d]pyrimidines and 6-amino-pyrazolo-[3,4-b]pyridines. The structure of the new derivatives was established by independent syntheses. The pyrazolo-pyrimidines can be cleaved with phosphoric acid to 3-amino-pyrazole-4-carboxamide derivatives. Many of the new pyrazolo-pyrimidines show an increase of coronary flow.
