Reaction Steps

As described for example 6, 5-(3-butyl-5-methyl-isoxazol-4-ylmethoxy)-2H-pyrazole-3-carboxylic acid methyl ester (100 mg, 0.34 mmol), instead of 5-(5-methyl-3-phenyl-isoxazol-4-ylmethoxy)-2H-pyrazole-3-carboxylic acid methyl ester, was converted, using L-alaninol instead of ethanolamine, to the title compound (7 mg, 6%) which was obtained as a colorless oil. MS: m/e=337.4 [M+H]+.
