Synthesis of Some Pyridothienopyrazolopyrimidopyrimidine and Mercaptomethylpyrazolopyrimidine Derivatives
摘要:
Mercaptomethylpyrazolopyrimidine (2) was synthesized and reacted with ethyl chloroacetate to afford ethyl pyrazolpyrimidinylmethylmercapto acetate (3), which in turn was converted into the corresponding carbohydrazide 4. Carbohydrazide 4 reacts with a variety of reagents to give different pyrazolopyrimidines (5-12). Chloromethyl-pyrazolopyrimidine (1) reacts with chloropyridine to give compound 13, which was subjected in a series of reactions to give new compounds 14-20.
