Procedure

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 N,N-dimethylacetamide (10 mL) at 100° C. for complete dissolution. The solution was then cooled to room temperature, and water (10 mL) was added dropwise thereto. The mixture was cooled to 5° C. 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 (2.3 g, yield 84.0%).
