Procedure

As described for example 14e, 3-(5-methyl-3-pyridin-2-yl-isoxazol-4-ylmethoxy)-isoxazole-5-carboxylic acid methyl ester (100 mg, 0.32 mmol) was converted, using ethanolamine (23 mg, 0.38 mmol) instead of isopropyl amine, to the title compound (90 mg, 82%) which was obtained as a white solid after purification by chromatography (silica, dichloromethane:methanol=1:0 to 9:1). MS: m/e=345.2 [M+H]+.
