Versuchsvorschrift
5-(4-Bromo-phenyl)-isoxazole-4-carboxylic acid ethyl ester (0.500 g, 1.69 mmol) was dissolved in concentrated hydrochloric acid (2 mL), acetic acid (5 mL), and H2O (5 mL), and the reaction was stirred at 100° C. overnight. The mixture was partitioned between EtOAc and H2O, and the organic layer was separated, dried over MgSO4, filtered, and concentrated to give the title compound.
