To a solution of 2-{[5-amino-4-(1,3-benzodioxol-5-yl)-1-methyl-1H-pyrazol-3-yl]oxy}ethyl acetate (100 mg) (Preparation 33) in ethanol (6 ml) at room temperature, was added sodium hydroxyde (100 mg). After one hour, the reaction was diluted with water (5 ml) and an aqueous saturated solution of ammonium chloride (10 ml). The mixture was extracted with ethyl acetate (3×6 ml). The organic fraction was dried over sodium sulfate and concentrated under reduced pressure to yield the title compound as a white solid (85 mg).
