実験手順

As described for example 85b, 5-(3-butyl-5-methyl-isoxazol-4-ylmethoxy)-2-methyl-2H-pyrazole-3-carboxylic acid methyl ester (60 mg, 0.2 mmol), was converted, using DL-2-amino-1-propanol instead of ethanolamine, to the title compound (48 mg, 70%) which was obtained as a colorless oil. MS: m/e=351.3 [M+H]+.
