Versuchsvorschrift
As described for example 249f, 6-(5-methyl-3-p-tolyl-isoxazol-4-ylmethoxy)-nicotinic acid methyl ester (250 mg, 0.73 mmol) was converted, instead of 6-(5-methyl-3-m-tolyl-isoxazol-4-ylmethoxy)-nicotinic acid methyl ester, to the title compound (260 mg, 84%) which was obtained as a white solid. MS: m/e=408.4 [M+H]+.
