Procedure
3.5 g of the tosylate salt of 4-{4-[({[4-chloro-3-(trifluoromethyl)phenyl]amino}carbonyl)-amino]phenoxy}-N-methylpyridine-2-carboxamide in the polymorph II are suspended in 15 ml of methanol and stirred at room temperature. After one week, the suspension is filtered and the residue dried at room temperature. Subsequently, the product is heat-treated at 150° C. for 30 min. The residue is analyzed by X-ray diffractometry and corresponds to the title compound in the polymorph III.
