Reaction Steps

As described for example 17e, 5-[3-(5-fluoro-pyridin-2-yl)-5-methyl-isoxazol-4-ylmethoxy]-2H-pyrazole-3-carboxylic acid methyl ester (100 mg, 0.3 mmol) was converted, using tert-butylamine instead of 2,2,2-trifluoroethylamine, to the title compound (25 mg, 22%) which was obtained as a white solid. MS: m/e=374.1 [M+H]+.
