As described for example 2, 5-methyl-3-phenyl-isoxazole-4-carboxylic acid hydrazide (200 mg, 0.92 mmol) was converted using 2-methoxybenzoic acid instead of o-toluic acid to the title compound (SiO2, heptane:ethyl acetate=95:5 to 50:50, 170 mg, 55%) which was obtained as a white foam. MS: m/e=334.0 [M+H]+.
