The invention relates to polymorphs of deuterated omega-diphenylurea or salts thereof. In particular, the invention provides polymorphs of 4-(4-3-[4-chloro-3-(trifluoromethyl)phenyl)-ureido]-phenoxy}-2-(N-1′,1′,1′-trideutero-methyl)picolinamide or its salt, namely, polymorphs of the compound as shown in formula (I) or its salt. The polymorphs are suited for preparing the pharmaceutical composition used for inhibiting phosphokinase (such as raf kinases).
本发明涉及氘代ω-二苯基脲或其盐的多晶形。具体而言,本发明提供了4-(4-3-[4-氯-3-(三氟甲基)苯基)-脲基]-苯氧}-2-(N-1′,1′,1′-三氘代甲基)吡啶甲酰胺或其盐的多晶形,即公式(I)化合物或其盐的多晶形。这些多晶形适用于制备用于抑制磷酸激酶(如raf激酶)的药物组合物。
