Procedure

As described for example 8b, 5-[3-(4-fluoro-phenyl)-5-methyl-isoxazol-4-ylmethoxy]-2H-pyrazole-3-carboxylic acid methyl ester (100 mg, 0.3 mmol) was converted, using isopropylamine instead of 4-aminomorpholine, to the title compound (50 mg, 46%), which was obtained as a white solid. MS: m/e=359.2 [M+H]+.
