실험 절차

As described for example 84d, 3-(2,5-difluoro-phenyl)-5-methyl-isoxazole-4-carboxylic acid ethyl ester (18 g, 67.4 mmol) was converted, instead of 3-(2-fluoro-phenyl)-5-methyl-isoxazole-4-carboxylic acid ethyl ester, to the title compound (3.25 g, 21%) which was obtained as a yellow oil. MS: m/e=226.2 [M+H]+.
