Procedure
As described for example 2, 5-methyl-3-phenyl-isoxazole-4-carboxylic acid hydrazide (200 mg, 0.92 mmol) was converted using 1H-benzoimidazole-4-carboxylic acid instead of o-toluic acid to the title compound (SiO2, dichloromethane:methanol:ammonia=95:5:0)=100:0 to 80:20, 32 mg, 10%) which was obtained as a white solid. MS: m/e=344.2 [M+H]+.
