Procedure

As described for example 84d, 5-methyl-3-m-tolyl-isoxazole-4-carboxylic acid ethyl ester (5.1 g, 20.8 mmol) was converted, instead of 3-(2-fluoro-phenyl)-5-methyl-isoxazole-4-carboxylic acid ethyl ester, to the title compound (3.2 g, 77%) which was obtained as a light yellow oil. MS: m/e=262.3 [M+OAc]−.
