Participants

Reaction Steps

As described for example 34, 3-(5-methyl-3-phenyl-isoxazol-4-ylmethoxy)-isothiazole-5-carboxylic acid methyl ester (100 mg, 0.3 mmol), was converted, using ethanolamine (21 mg, 0.34 mmol), instead of isopropyl amine, to the title compound (60 mg, 58%) which was obtained as a white solid after purification by chromatography (silica, dichloromethane:methanol=1:0 to 9:1). MS: m/e=360.1 [M+H]+.
