실험 절차
To 1-(4-{3-[(2R)-2-methylpyrrolidin-1-yl]propoxy}phenyl)-1H-pyrazole-4-carboxylic acid ethyl ester obtained in Example 1-(3) (1.11 g), concentrated hydrochloric acid (7.0 mL) was added at room temperature and stirred at 80° C. for 2 hours. The reaction mixture was concentrated under reduced pressure to give the titled compound (1.08 g) as a light-brown solid.
