Summary:The invention discloses a method for preparing a ticagrelor solution. According to the invention, hydroxy of a ticagrelor I crude product is protected by a protective group, then a crude product of a compound II is separated and purified to obtain the high purity compound II; the hydroxy protective group of the high purity compound II is removed under proper reaction conditions, a reaction mixture is post-processed and then the by-product is removed to obtain the high purity ticagrelor I, the ticagrelor I, a solvent or/and pharmaceutic adjuvant form a solution, after the solvent is removed, ticagrelor or a mixture containing ticagrelor and accessory with medicinal requirement can be obtained. The method has the advantages of mild reaction condition, simple operation, low cost, and environmental protection, and is suitable for industrial production. 本发明公开了种替格瑞洛溶液的制备方法,将替格瑞洛I粗品的羟基经保护基保护,然后将得到的化合物II的粗品进行分离纯化,得到高纯度化合物II;再将高纯度化合物II在合适的反应条件下脱除羟基保护基,反应混合物经后处理并去除副产物,得到满足药用的高纯度的替格瑞洛I,其与溶剂或者与溶剂和药用辅料形成溶液,该溶液脱除溶剂后,可以得到满足
