Versuchsvorschrift

N-{2-Chloro-4-[(6,7-dimethoxy-4-quinolyl)oxy]phenyl}-N′-(5-methyl-3-isoxazolyl)urea (2.0 g) produced in Production Example was added to acetonitrile (27 mL), a solution of p-toluenesulfonic acid monohydrate (2.5 g) in acetonitrile (27 mL) was added dropwise thereto, and the mixture was stirred at room temperature for 3 hr. The resultant precipitate was collected by filtration and the filtered product was then dried under the reduced pressure. The powder thus obtained was stirred in methanol (160 mL) under reflux for complete dissolution. The solution was then cooled to room temperature and was stirred at that temperature overnight. The resultant precipitate was filtered, and the filtered product was then dried under the reduced pressure to give a form II crystal of N-{2-chloro-4-[(6,7-dimethoxy-4-quinolyl)oxy]phenyl}-N′-(5-methyl-3-isoxazolyl)urea p-toluenesulfonate (2.0 g, yield 74.0%).
