The invention relates to dihydropyrazolon-derivatives of formula (I), to methods for their production, to their use for treating and/or for preventing diseases and their use for producing medicaments for treating and/or for preventing diseases, in particular cardiovascular and haematological diseases, kidney diseases and for promoting the healing of wounds.
Starting from sodium azide, methyl-bromoacetate, and 3-methylbut-1-yne, a safe and efficient three-step continuous process was developed to obtain 2-(4-isopropyl-1H-1,2,3-triazol-1-yl)aceticacid. Isolation of hazardous intermediates was avoided, and by using FT-IR in-line monitoring of the azides involved, risks associated with these components were minimized. Furthermore, the use of FT-IR as a tool
从叠氮化钠,溴乙酸甲酯和3-甲基丁-1-炔开始,开发了一种安全有效的三步连续方法,以获得2-(4-异丙基-1 H -1,2,3-三唑-1 -基)乙酸。避免了危险中间体的分离,并且通过使用FT-IR在线监测所涉及的叠氮化物,将与这些组分相关的风险降至最低。此外,使用FT-IR作为实时优化工具有助于对反应步骤动力学的理解,并导致参数的快速优化。连续法用于三唑的数百克生产,三唑被用作我们药物开发项目之一的关键组成部分。
