Synthesis of some pyrazolo[3,4-d]pyrimidine derivatives for biological evaluation
Shamroukh,Rashad,Sayed
, p. 2347 - 2360 (2005)
A novel β-enaminonitrile of 1-(6-p-tolyl-pyridazin-3-yl)-pyrazole derivative 2 was formed using (6-p-tolyl-pyridazin-3-yl)-hydrazine (1) and 2-ethoxymethylenemalononitrile. The β-enaminonitrile derivative 2 was in turn used as a precursor for the preparat
