Procedure
As described for example 26d, 5-(3-butyl-5-methyl-isoxazol-4-ylmethoxy)-2H-pyrazole-3-carboxylic acid methyl ester (100 mg, 0.34 mmol) was converted, using isopropylamine instead of 4-aminotetrahydropyran, to the title compound (97 mg, 89%) which was obtained as a colorless oil. MS: m/e=321.3 [M+H]+.
