Procedure

To a solution of tert-butyl N-(2-hydroxyethyl)-N-{[1-(4-{3-[(2R)-2-methylpyrrolidin-1-yl]propoxy}phenyl)-1H-pyrazol-4-yl]carbonyl}glycinate prepared in Example 67-(3) (0.218 g) in 1,4-dioxane (4.0 ml), a solution of hydrochloric acid in ethyl acetate (4 M, 4.0 ml) was added and stirred at room temperature for 1 hour. The reaction mixture was concentrated under reduced pressure, and the resulting residue was purified by octadecylsilyl (ODS) column chromatography (eluting solvent: acetonitrile:water=95:5) to give the titled compound (0.075 g) as a colorless amorphous substance.
