Zusammenfassung:Disclosed are novel novel polymorphic solvated and desolvated forms of the sodium salt of 4-tert-butyl-N-[ 4-chloro-2-(1-oxy-pyridine-4-carbonyl)phenyl]-benzenesulfonamide. One embodiment of the present invention is directed to a crystalline sodium salt of 4-tert-butyl-N-[ 4-chloro-2-(1-oxy-pyridine-4-carbonyl)-phenyl]benzenesulfonamide (hereinafter "Compound A-l,4-dioxane/water solvate"), wherein the crystalline form is characterized by an X-ray powder diffraction pattern comprising diffraction angles (°28), when measured using Cu Ku radiation, at about 4.0,8.1, 10.1, 14.2, 16.2, 18.6,20.3,24.7,25.0, and 26.5.
