Procedure

As described for example 2, 5-methyl-3-phenyl-isoxazole-4-carboxylic acid hydrazide (5.00 g, 23.0 mmol) was converted using 4-fluorobenzoic acid instead of o-toluic acid to the title compound (recrystallisation from tert-butylmethylether, 2.98 g, 40%) which was obtained as an off-white solid. MS: m/e=322.2 [M+H]+.
