As described for example 1b, 2-methyl-5-[5-methyl-3-(tetrahydro-pyran-4-yl)-isoxazol-4-ylmethoxy]-2H-pyrazole-3-carboxylic acid methyl ester (200 mg, 0.6 mmol), instead of 5-(5-methyl-3-phenyl-isoxazol-4-ylmethoxy)-2H-pyrazole-3-carboxylic acid methyl ester, was converted, using 4-aminotetrahydropyran instead of morpholine, to the title compound (183 mg, 76%) which was obtained as a colorless gum. MS: m/e=403.1 [M−H]−.
