Procedure

As described for example 10a, 5-[3-(5-fluoro-pyridin-2-yl)-5-methyl-isoxazol-4-ylmethoxy]-2H-pyrazole-3-carboxylic acid methyl ester (50 mg, 0.15 mmol), instead of 5-[3-(4-fluoro-phenyl)-5-methyl-isoxazol-4-ylmethoxy]-2H-pyrazole-3-carboxylic acid methyl ester, was converted, to the title compound (38 mg, 79%) which was obtained as a white solid. MS: m/e=317.0 [M−H]−.
