As described for example 2b, 5-[3-(5-fluoro-pyridin-2-yl)-5-methyl-isoxazol-4-ylmethoxy]-pyrazine-2-carboxylic acid (44 mg, 13.3 mmol), instead of 5-(5-methyl-3-phenyl-isoxazol-4-ylmethoxy)-pyrazine-2-carboxylic acid, was converted, using 4-aminotetrahydropyran instead of aminomethylcyclopropane, to the title compound (SiO2, ethyl acetate then DCM:MeOH=90:10, 31 mg, 56%) which was obtained as a white solid. MS: m/e=414.2 [M+H]+.
