    • This invention provides a novel dicarboxylic acid salt forms of varenicline, namely varenicline fumarate, and methods for making same. Varenicline salts are useful for treating smoking addition. In one embodiment of the instant invention, the varenicline fumarate shows an XRD pattern (2θ)) (±0.2° having characteristic peaks at 10.6, 11.9, 13.2, 16.2, 16.6, 18.0, 21.5, 22.6, 25.7, 28.5 and 29.1°. In another embodiment, the varenicline fumarate is prepared by (i) contacting varenicline with fumaric acid, optionally in the presence of a suitable solvent, and removing the solvent when necessary, or (ii) contacting varenicline fumarate salt with a suitable solvent, and removing the solvent.
    • 本发明提供了一种新的二甲酸盐形式的伐伦尼克林,即富马酸伐曼尼克林及其制备方法。 伐尼克星盐可用于治疗吸烟。 在本发明的一个实施方案中,富马酸伐伦碱显示XRD图谱(2θ))(±0.2°,在10.6,11.9,13.2,16.2,16.6,18.0,21.5,22.6,25.7,28.5和29.1°具有特征峰。 在另一个实施方案中,富马酸伐伦碱通过以下步骤制备:(i)任选地在合适的溶剂存在下使伐伦尼克兰与富马酸接触,并在必要时除去溶剂,或(ii)将富马酸伐伦碱与合适的溶剂接触, 溶剂。
