Versuchsvorschrift
As described for example 4, (5-methyl-3-phenyl-isoxazol-4-yl)-methanol (313 mg, 1.66 mmol) was converted using 6-hydroxy-2-methyl-nicotinic acid ethyl ester instead of 2-hydroxy-5-trifluoromethylpyridine to the title compound (SiO2, heptane:ethyl acetate=60:40 to 10:90, 322 mg, 55%) which was obtained as a colourless oil. MS: m/e=353.2 [M+H]+.
