Procedure
As described for example 2, 5-methyl-3-phenyl-isoxazole-4-carboxylic acid hydrazide (200 mg, 0.92 mmol) was converted using 3-(methylsulfonyl)-benzoic acid instead of o-toluic acid to the title compound (SiO2, heptane:ethyl acetate:dichloromethane=50:30:20 to 20:60:20, 44 mg, 13%) which was obtained as a white solid. MS: m/e=382.1 [M+H]+.
