実験手順
As described for example 91a, 6-[3-(4-fluoro-phenyl)-5-methyl-isoxazol-4-ylmethoxy]-nicotinic acid methyl ester (1.4 g, 4.2 mmol), instead of 6-[3-(3-fluoro-phenyl)-5-methyl-isoxazol-4-ylmethoxy]-nicotinic acid methyl ester, was converted, to the title compound (1.1 g, 78%) which was obtained as a white solid. MS: m/e=327.3 [M−H]−.
