Participants

Reaction Steps

As described for example 14e, 3-[3-(5-fluoro-pyridin-2-yl)-5-methyl-isoxazol-4-ylmethoxy]-isoxazole-5-carboxylic acid methyl ester (100 mg, 0.3 mmol), instead of 3-(5-methyl-3-pyridin-2-yl-isoxazol-4-ylmethoxy)-isoxazole-5-carboxylic acid methyl ester, was converted, using isopropyl amine (21 mg, 0.36 mmol), to the title compound (95 mg, 88%) which was obtained as a white solid after purification by chromatography (silica, dichloromethane:methanol=1:0 to 9:1). MS: m/e=361.2 [M+H]+.
