As described for example 114d, 5-[3-(5-fluoro-pyridin-2-yl)-5-methyl-isoxazol-4-ylmethoxy]-1-methyl-1H-pyrazole-3-carboxylic acid methyl ester (100 mg, 0.29 mmol), instead of 1-methyl-5-(5-methyl-3-pyridin-2-yl-isoxazol-4-ylmethoxy)-1H-pyrazole-3-carboxylic acid methyl ester, was converted, to the title compound (66 mg, 59%) which was obtained as a colorless oil.
