    • The present invention relates to crystalline forms of 11 beta(4-acetylphenyl)-20,20,21,21, 21-pentafluor-17-hydroxy-19-nor-17alpha-pregna-4,9-dien-3-one. In particular, the invention relates to two crystalline ansolvate/anhydrate forms of this compound, polymorphs I and II. However, the present invention also relates to crystalline solvates, for example, methanol and ethanol solvates of 11 beta(4-acetylphenyl)-20,20,21,21,21-pentafluor-17-hydroxy-19-nor-17alpha-pregna-4,9-dien-3-one, as precursors for the preparation of these two polymorphs I and II. Processes are described for the preparation of polymorph I by means of displacement crystallization or by means of extraction. The choice of the last solvent, before the ansolvate formation can take place, on the basis of the differences in the purification ratios of the individual solvates of 11 beta(4-acetylphenyl)-20,20,21,21, 21-pentafluor-17-hydroxy-19-nor-17alpha-pregna-4,9-dien-3-one is described. Polymorph I, according to the invention, is particularly suitable for the preparation of drugs.
    • 本发明涉及11β(4-乙酰基苯基)-20,20,21,21,21-五氟-17-羟基-19-去甲-17α-孕甾-4,9-二烯-3-酮的结晶形式。 特别地,本发明涉及这种化合物的两种结晶的无水物/无水物形式,即多晶型物I和II。 然而,本发明还涉及结晶溶剂化物,例如11β(4-乙酰基苯基)-20,20,21,21,21-五氟-17-羟基-19-去甲基-alpha-pregna的甲醇和乙醇溶剂合物 -4,9-二烯-3-酮作为制备这两种多晶型物I和II的前体。 描述了通过置换结晶或通过萃取制备多晶型I的方法。 根据11β(4-乙酰基苯基)-20,20,21,21,21-五氟-2-甲基苯酚的各个溶剂合物的纯化比例的差异,可以在固体形成之前进行最后一种溶剂的选择, 描述了17-羟基-19-去甲-17α-孕甾-4,9-二烯-3-酮。 根据本发明的多晶型I特别适用于制备药物。
