Novel glycopyrronium fatty acid salts have been developed. Bi-phasic reaction conditions enable the desired counterion exchange reactions between glycopyrronium bromide and fatty acid salts of alkali metals and alkaline earth metals in methods to form glycopyrronium fatty acid salts. In preferred embodiments, an excess of the free fatty acid in the reaction mixture stabilizes the glycopyrronium fatty acid salt and reduces the formation of the impurity, Acid A. In some preferred embodiments, between 0.2 and 1.2 molar equivalent of excess free fatty acid is added to the reaction mixture. In another embodiment, approximately 1.2 molar equivalent of excess free fatty acid is added to the reaction mixture.
新型甘草酸铵脂肪酸盐已经研制成功。双相反应条件使溴化甘草酸铵与碱金属和碱土金属的脂肪酸盐之间发生所需的反离子交换反应,从而形成甘草酸铵脂肪酸盐。在优选的实施方案中,反应混合物中过量的游离脂肪酸可以稳定甘草酸铵脂肪酸盐,减少杂质酸 A 的形成。在另一个实施方案中,向反应混合物中加入约 1.2 摩尔当量的过量游离脂肪酸。
