Procedure
As described for example 2, 5-methyl-3-phenyl-isoxazole-4-carboxylic acid hydrazide (500 mg, 2.30 mmol) was converted using indole-5-carboxylic acid instead of o-toluic acid to the title compound (SiO2, heptane:ethyl acetate:dichloromethane=70:10:20 to 40:40:20, 430 mg, 55%) which was obtained as a colorless liquid. MS: m/e=343.1 [M+H]+.
