Versuchsvorschrift

Crude 3-(4-hydroxy-phenyl)-isoxazole-5-carboxylic acid ethyl ester (which may be prepared as described in Preparation of Intermediate 1; 1.9 g, 8.15 mmol) was taken up in a solution of EtOH saturated with NH3. The mixture was stirred overnight at room temperature under nitrogen. The solvent was evaporated to give 3-(4-hydroxy-phenyl)-isoxazole-5-carboxylic acid amide (1.17 g, 70%) as a flaky white powder.
