The invention provides methods of chemical synthesis of the pharmacological agent 2-[4-[(2,3,4-trimethoxyphenyl)methyl]piperazin-1-yl]ethyl pyridine-3-carboxylate, also called CV-8972. The methods entail formation of a free base form of 2-[4-[(2,3,4-trimethoxyphenyl)methyl]piperazin-1-yl]ethanol, also called CV-8814, as intermediate without producing a salt form of CV-8814.
本发明提供了一种化学合成药理学药物2-[4-[(2,3,4-三甲氧基苯基)甲基]哌嗪-1-基]乙基吡啶-3-羧酸酯(也称为CV-8972)的方法。该方法涉及形成2-[4-[(2,3,4-三甲氧基苯基)甲基]哌嗪-1-基]乙醇的自由碱基形式(也称为CV-8814)作为中间体,而不产生CV-8814的盐形式。
