Procedure

As described for example 2, 5-methyl-3-phenyl-isoxazole-4-carboxylic acid hydrazide (500 mg, 2.30 mmol) was converted using 2,6-dimethoxynicotinic acid instead of o-toluic acid to the title compound (SiO2, heptane:ethyl acetate=80:20 to 40:60, 204 mg, 24%) which was obtained as a white solid. MS: m/e=365.2 [M+H]+.
