Abstract:
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).
