Reaction Steps

As described for example 92, 6-(5-methyl-3-pyridin-4-yl-isoxazol-4-ylmethoxy)-nicotinic acid (93 mg, 0.3 mmol), instead of 6-[3-(3-fluoro-phenyl)-5-methyl-isoxazol-4-ylmethoxy]-nicotinic acid methyl ester (103 mg, 0.3 mmol) was converted, using 2,2,2-trifluoroethylamine instead of cyclopropylamine, to the title compound (16 mg, 14%) which was obtained as a light brown solid. MS: m/e=393.3 [M+H]+.
