Procedure
As described for example 127, 2-(5-methyl-3-phenyl-isoxazol-4-ylmethoxy)-thiazole-5-carboxylic acid ethyl ester (100 mg, 0.28 mmol) was converted, using ethanolamine instead of isopropylamine, to the title compound (62 mg, 59%) which was obtained as a colourless gum after purification by chromatography (silica, 0 to 3% methanol in dichloromethane). MS: m/e=360.3 [M+H]+.
