The invention relates to the new co crystals of 5-chloro-N-///5S/-2-oxo-3-/4-/3- oxo-moφholine-4-yl/-phenyl/-l,3-oxazolidine-5-yl/-methyl/-thiophen-2- carboxamide having the INN rivaroxaban formed with oxalic acid and gamma- cyclodextrine. The invention also relates to a process for the preparation of the co crystal of rivaroxaban and oxalic acid of the Formula 2. According to said process amorphous or crystalline rovaroxaban or a hydrate, solvate or co crystal of rivaroxaban is dissolved in an organic solvent, water or a mixture of an organic solvent and water, to the solution oxalic acid is added and the solvent is removed. According to the invention there is also provided a process for the preparation of the co crystal of rivaroxaban and gamma-cyclodextrin of the Formula 3 /wherein n is 0.9-1.1, preferably n=l/. According to said process amorphous or crystalline rivaroxaban or a hydrate, solvate or co crystal of rivaroxaban is dissolved in an organic solvent, water or a mixture of an organic solvent and water, to the solution gamma-cyclodextrine is added and the solvent is removed.
该发明涉及与草酸和γ-环糊精形成的INN利伐沙班的新共晶体,其是5-氯-N-///5S/-2-氧代-3-/4-/3-氧代-吗啉-4-基-苯基-1,3-噁唑啉-5-基-甲基-噻吩-2-羧酰胺的新共晶体。该发明还涉及制备利伐沙班和草酸的共晶体的方法。根据该方法,非晶态或结晶利伐沙班或利伐沙班的水合物、溶剂合物或共晶体溶解在有机溶剂、水或有机溶剂和水的混合物中,向溶液中加入草酸并去除溶剂。根据该发明,还提供了制备利伐沙班和γ-环糊精的共晶体的方法。根据该方法,非晶态或结晶利伐沙班或利伐沙班的水合物、溶剂合物或共晶体溶解在有机溶剂、水或有机溶剂和水的混合物中,向溶液中加入γ-环糊精并去除溶剂。
