Procedure

A suspension of 1-(4-{3-[(2R)-2-methylpyrrolidin-1-yl]propoxy}phenyl)-1H-pyrazol-4-ylamine obtained in Example 29-(1) (0.191 g), 4-hydroxybenzoic acid (0.097 g), 1-hydroxybenzotriazole monohydrate (0.107 g) and 3-(3-dimethylaminopropyl)-1-ethylcarbodiimide hydrochloride (0.18 g) in chloroform (6.4 mL) was stirred at room temperature for 4 days. The reaction mixture was concentrated under reduced pressure, and the residue was purified by NH-type silica gel column chromatography (eluting solvent: chloroform→chloroform:methanol=10:1) to give the titled compound (0.137 g) as a colorless amorphous substance.
