根据本发明,作为原料的所述式(I)和/或其盐指其固体(晶体或无定形)、半固体、蜡或油形式。优选地,作为原料的化合物和/或其盐为固体粉末形式。所述“搅拌”,采用本领域的常规方法完成,例如磁力搅拌或机械搅拌,搅拌速度为50-1800转/分钟,其中,磁力搅拌优选为300-1000转/分钟,机械搅拌优选为100-300转/分钟。
本发明中,“晶体”或“多晶型”指的是被所示的X射线衍射图表征所证实的。本领域技术人员能够理解,这里所讨论的理化性质可以被表征,其中的实验误差取决于仪器的条件、样品的准备和样品的纯度。特别是,本领域技术人员公知,X射线衍射图通常会随着仪器的条件而有所改变。特别需要指出的是,X射线衍射图的相对强度也可能随着实验条件的变化而变化,所以峰强度的顺序不能作为唯一或决定性因素。事实上,XRPD图谱中衍射峰的相对强度与晶体的择优取向有关,本文所示的峰强度为说明性而非用于绝对比较。另外,峰角度的实验误差通常在5%或更少,这些角度的误差也应该被考虑进去,通常允许有±0.2°的误差。另外,由于样品厚度等实验因素的影响,会造成峰角度的整体偏移,通常允许一定的偏移。因而,本领域技术人员可以理解的是,本发明中一个晶型的X射线衍射图不必和这里所指的例子中的X射线衍射图完全一致,本文所述“XRPD图相同”并非指绝对相同,相同峰位置可相差±0.2°且峰强度允许一定可变性。任何具有和这些图谱中的特征峰相同或相似的图的晶型均属于本发明的范畴之内。本领域技术人员能够将本发明所列的图谱和一个未知晶型的图谱相比较,以证实这两组图谱反映的是相同还是不同的晶型。
在一些实施方案中,本发明的晶型C,晶型A,晶型Y,晶型V,晶型AE,晶型AA,是纯的、单一的,基本没有混合任何其他晶型。本发明中,“基本没有”当用来指新晶型时指这个晶型含有少于20%(重量)的其他晶型,尤其指少于10%(重量)的其他晶型,更指少于5%(重量)的其他晶型,更指少于1%(重量)的其他晶型。
需要说明的是,本发明中提及的数值及数值范围不应被狭隘地理解为数值或数值范围本身,本领域技术人员应当理解其可以根据具体技术环境的不同,在不背离本发明精神和原则的基础上围绕具体数值有所浮动,本发明中,这种本领域技术人员可预见的浮动范围多以术语“约”来表示。
本发明提供的式(I)晶型C,晶型A,晶型Y,晶型V,晶型AE,晶型AA,在溶解度、熔点、稳定性、溶出度、引湿性、黏附性、流动性、生物有效性以及加工性能、提纯作用、制剂生产、安全性等方面中的至少一方面上存在优势,为含式(I)化合物的药物制剂的制备提供了新的更好的选择,对于药物开发具有非常重要的意义。
与现有技术相比,发明提供的式(I)化合物的新晶型,在溶解度、熔点、稳定性、溶出 度、引湿性、黏附性、流动性、生物有效性以及加工性能、提纯作用、制剂生产、安全性等方面中的至少一方面上存在优势,为BTK抑制剂的药物制剂的制备提供了新的更好的选择,对于药物开发具有非常重要的意义。

以下将通过具体实施例进一步阐述本发明,但并不用于限制本发明的保护范围。本领域技术人员可在权利要求范围内对制备方法和使用仪器作出改进,这些改进也应视为本发明的保护范围。因此,本发明专利的保护范围应以所附权利要求为准。
