    The subject of this invention provides a method of preparation and isolation of water-insoluble or partially soluble salts of vardenafil of formula 1, in particular its salts with acids in the ratio of components 1 : 1 (of formula 2a, HA stands for any acid), and of crystalline hydrates of said salts. These solid forms, in particular crystalline vardenafil hydrochloride trihydrate of formula 4, can be directly, without additional purification, used in preparation of a medicine for the therapy of erectile dysfunction. The present solution is based on using water as a suitable medium both for obtaining of extracts of the water-soluble forms of vardenafil, and for isolation and subsequent crystallization of solid water-insoluble or partially soluble salts of vardenafil with acids (1 : 1). Crystallization of the isolated salts takes place after adjustment of pH of the aqueous solutions by means of aqueous solutions of bases or acids, wherein no organic solvent or a mixture thereof with water is needed for the crystallization. The method according to this invention reduces costs for organic solvents, increases efficiency of isolation of the vardenafil salts with acids, and facilitates preparation of poorly stable hydrates of these salts.
    本发明的主题提供了一种制备和分离公式1的伐地那非水不溶性或部分可溶性盐的方法,特别是其与酸的成分比为1:1的盐(公式2a中,HA代表任何酸),以及所述盐的结晶水合物。这些固体形式,特别是公式4的结晶伐地那非盐酸盐三水合物,可以直接用于治疗勃起功能障碍的药物制剂的制备,无需额外的纯化。本发明的解决方案基于使用水作为合适的介质,既可以获得伐地那非水溶性形式的提取物,又可以分离和随后结晶伐地那非与酸(1:1)的固体水不溶性或部分可溶性盐。通过使用水溶液的碱或酸的调节,无需有机溶剂或其与水的混合物进行结晶。本发明的方法降低了有机溶剂的成本,提高了伐地那非与酸的盐的分离效率,并促进了这些盐的不稳定水合物的制备。
