CRYSTALLINE FORMS OF 3-(2,6-DICHLORO-3,5-DIMETHOXY-PHENYL)-1-{6-[4-(4-ETHYL-PIPERAZIN-1-YL)-PHENYLAMINO]-PYRIMIDIN-4-YL}-1-METHYL-UREA AND SALTS THEREOF

摘要

CRYSTALLINE FORMS OF 3-f2,6-PICHLORO-3,5-DIMETHOXY-PHENYLH~f6-r4-(4-ETHYL- PIPERAZIN-1-YL)-PHENYLAMINQ1-PYRIMIDlN-4-YLVt-METHYL-UREA AND SALTS THEREOF The present technology provides novel anhydrous and hydrated crystalline forms of 3-(2,6-dichioro- 3,5-dimethoxy-phenyl)-1-{6-[4-(4-ethyl-piperazin-1-yl)-phenylamino]-pyrimidin-4-yl}-1-methykjrea, amorphous and anhydrous crystalline polymorphs of its monophosphoric acid salt, and the hydrochloride salt, including its dihydrate. The present technology further provides methods for preparing the various forms, compositions containing them, and methods of treatment employing them. No Figure
