Reaction Steps
As described for example 286c, 3-(5-chloro-pyridin-2-yl)-5-methyl-isoxazole-4-carboxylic acid ethyl ester (1.26 g, 4.7 mmol) was converted, instead of 3-(5-fluoro-pyridin-2-yl)-5-methyl-isoxazole-4-carboxylic acid ethyl ester, to the title compound (773 mg, 73%) which was obtained as an off white solid. MS: m/e=224.9 [M+H]+.
