Reaction Steps

As described for example 1b, 2-methyl-5-(5-methyl-3-phenyl-isoxazol-4-ylmethoxy)-2H-pyrazole-3-carboxylic acid methyl ester (30 mg, 0.09 mmol), instead of 5-(5-methyl-3-phenyl-isoxazol-4-ylmethoxy)-2H-pyrazole-3-carboxylic acid methyl ester, was converted, using rac-3-aminotetrahydrofuran instead of morpholine, to the title compound (28 mg, 80%) which was obtained as a colorless oil. MS: m/e=383.2 [M+H]+.
