NOVEL CRYSTAL FORMS OF 4-(2-AMINOPYRIDIN-4-YL)-3-(4-FLUOROPHENYL)-1-(1,4,5,6-TETRAHYDRO-6-OXOPYRIDAZIN-3-YL)-1H-PYRAZOLE METHANESULFONATE AND METHODS FOR THEIR PREPARATION

摘要

Novel crystal forms of 4-(2-aminopyridin-4-yl)-3-(4- fluorophenyl)-1-(1,4,5,6-tetrahydro-6-oxopyridazin-3-yl)-1H-pyrazole methanesulfonate, which are useful as medicines; and a process for production of same. Two stable polymorphic forms called A-type crystal and B-type crystal; and a process for production by which the polymorphic forms can be each produced as a single polymorphic form.
