3-(3-(4-(Pyridin-2-yloxymethyl)-benzyl)-isoxazol-5-yl)-pyridin-2-yl amine (200 mg) was dissolved in methanol and ethyl acetate, and an aqueous solution of hydrobromic acid (1.16N,0.90 mL) was added thereto. The solvent was concentrated under a reduced pressure. To the residue was added toluene, and concentrated under a reduced pressure. To the residue was added ethanol, and concentrated under a reduced pressure. To the residue was added a small amount of ethanol, then subjected to ultrasound treatment to be solidified. The solids were filtered to obtain the title compound (255 mg).
