Reaction Steps

To a solution of 1-(4-{3-[(2R)-2-methylpyrrolidin-1-yl]propoxy}phenyl)-1H-pyrazole-4-carboxylic acid methoxymethylamide obtained in Example 23-(1) (0.25 g) in tetrahydrofuran (3 mL), a solution of 4-fluorophenylmagnesium bromide in tetrahydrofuran (1.0 M, 4.0 mL) was added dropwise in an ice bath and stirred at room temperature for 2 hours. The reaction mixture was diluted with saturated aqueous ammonium chloride and extracted with chloroform. The organic layer was dried over sodium sulfate and concentrated under reduced pressure, and the resulting residue was purified by NH-type silica gel column chromatography (eluting solvent: hexane:ethyl acetate=5:1 to 4:1) and silica gel column chromatography (eluting solvent: chloroform:methanol=95:5) to give the titled compound (0.11 g) as a light-blue solid.
