Versuchsvorschrift

A total of 25.6 mg of C-{3-(3-fluoro-phenyl)-6-methoxy-1H-indazol-5-yl}-methylamine obtained in Production Example II-26 was dissolved in 1.9 ml of dimethylformamide, 15.3 mg of 1-hydroxybenzotriazole, 0.066 ml of diisopropylethylamine and 14.4 mg of 3-methoxybenzoic acid were added thereto, and 27.2 mg of 1-ethyl-3-(3′-dimethylaminopropyl)carbodiimide hydrochloride (i.e., WSC.HCl) was added thereto under ice-cooling and stirring. After stirring at room temperature for 5 hours, water was added and the mixture was extracted with ethyl acetate. The resulting organic layer was washed with 0.5 N aqueous sodium hydroxide solution, 1 N hydrochloric acid and saturated brine, dried over magnesium sulfate, and the solvent was evaporated. The residue was purified and separated by silica gel column chromatography (dichloromethane:methanol=10:1), to give 9.24 mg of the title compound as pale yellow crystals.
