Procedure

As described for example 2, 5-methyl-3-phenyl-isoxazole-4-carboxylic acid hydrazide (200 mg, 0.92 mmol) was converted using 2-methoxy-4-methyl-benzoic acid instead of o-toluic acid to the title compound (SiO2, heptane:ethyl acetate:dichloromethane=75:5:20 to 60:20:20, 155 mg, 48%) which was obtained as a white solid. MS: m/e=348.2 [M+H]+.
