A general two-stepsynthesis of substituted 3-aminoindazoles from 2-bromobenzonitriles involving a palladium-catalyzed arylation of benzophenone hydrazone followed by an acidic deprotection/cyclization sequence is described. This procedure offers a general and efficient alternative to the typical SNAr reaction of hydrazine with o-fluorobenzonitriles.
描述了由2-溴苯甲腈进行的一般两步合成取代的3-氨基吲唑,涉及钯催化的二苯甲酮的芳基化,然后进行酸性脱保护/环化序列。该方法为肼与邻氟苄腈的典型S N Ar反应提供了一种通用而有效的替代方法。

Flow chemistry is a rapidly emerging technology within the pharmaceutical industry, both within medicinal and development chemistry groups. The advantages of flow chemistry, increased safety, improved reproducibility, enhanced scalability, are readily apparent, and we aimed to exploit this technology in order to provide small amounts of pharmaceutically interesting fragments via a safe and scalable
