A series of novel 1-arylpyrazolo[3,4-d]pyrimidine derivatives, containing an amide moiety, was synthesised by condensation of different acids with 1-(2,4-dichlorophenyl)-1H-pyrazolo[3,4-d]pyrimidin-4-amine. This intermediate was prepared from 5-amino-1-(2,4-dichlorophenyl)-1H-pyrazole-4-carbonitrile by condensation with triethyl orthoformate and then cyclisation with ammonium hydroxide solution in
通过不同酸与 1-(2,4-二氯苯基)-1H-吡唑并 [3,4-d] 缩合合成了一系列含有酰胺部分的新型 1-芳基吡唑并[3,4-d]嘧啶衍生物嘧啶-4-胺。该中间体由 5-氨基-1-(2,4-二氯苯基)-1H-吡唑-4-甲腈通过与原甲酸三乙酯缩合,然后在室温下与四氢呋喃中的氢氧化铵溶液环化而制备。此外,含有酰胺部分的1-芳基吡唑并[3,4-d]嘧啶的分子结构是通过单晶X射线衍射确定的。
