A microwave-mediated synthesis of 1H-pyrazole-5-amines utilizing 1 M HCl at 150 °C was developed in order to provide products in a matter of minutes with minimal purification. Most reactions are complete in only 10 min and can be isolated via a simple filtration without the need for further purification by column chromatography or recrystallization. This method tolerates a range of functional groups
为了在几分钟内以最少的纯化提供产物,开发了利用1 M HCl在150°C的微波介导的1 H-吡唑5-胺的合成方法。大多数反应仅在10分钟内即可完成,可以通过简单的过滤进行分离,而无需通过柱色谱法或重结晶法进一步纯化。该方法可耐受一定范围的官能团,并且可以以毫克至克为单位进行测量。

Benzoylacetonitrile and beta-aminocinnamonitrile are shown to possess potent antiinflammatory activity in the rat adjuvant arthritis model. In a series of phenyl-substituted analogues, only o-, m-, and p-fluorobenzoylacetonitrile and m- and p-fluoro-beta-aminocinnamonitrile retained activity. Additionally, beta-amino-2- and beta-amino-3-thiopheneacrylonitrile and beta-oxo-2- and beta-oxo-3-thiophenepropionitrile
