Upon controlled microwave heating and using cyanuric chloride as a coupling reagent, an efficient amidation procedure for the synthesis of 1,3-dihydro-2H-benzo[d]imidazol-2-one-based agonists of TRPC3/6 ion channels has been developed. Compared to the few conventional protocols, a drastic reduction in processing time from ca. 2 days down to 10 minutes was achieved accompanied by significantly improved
在控制微波加热和使用三聚氯氰作为偶联剂的情况下,开发了一种有效的酰胺化方法,用于合成 1,3-二氢-2H-苯并[d]咪唑-2-酮基 TRPC3/6 离子通道激动剂. 与少数传统协议相比,处理时间大幅缩短。实现了 2 天缩短到 10 分钟,同时显着提高了产品产量。该方法的稳健性得到了 18 个其他示例的证实,包括芳香族、脂肪族和杂环胺和酸。在 1 μM 浓度下筛选获得的激动剂的生物活性,并建立了很少的构效关系。
