실험 절차

To a suspension of 1-(4-{3-[(2R)-2-methylpyrrolidin-1-yl]propoxy}phenyl)-1H-pyrazole-4-carboxylic acid hydrochloride obtained in Example 2-(1) (1.08 g) in N,N-dimethylformamide (11 mL), 1-hydroxybenzotriazole monohydrate (0.539 g) was added at room temperature and stirred for 5 minutes. To the reaction mixture, 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (0.679 g) was added and stirred at room temperature for 30 minutes, followed by addition of aqueous ammonia (25%, 0.702 g) and stirring overnight at room temperature. After addition of water and saturated aqueous sodium bicarbonate, the reaction mixture was extracted with ethyl acetate. The organic layer was washed with water and brine, dried over sodium sulfate and concentrated under reduced pressure. The resulting residue was purified by silica gel column chromatography (eluting solvent: chloroform:methanol=20:1) to give the titled compound (0.504 g) as a colorless solid.
