실험 절차

A solution of ethyl (5-(methoxycarbonyl)isoxazol-3-yl)oxyacetate (4 mmol, Example 73) in methanol (60 mL) and 5% aqueous NaOH is heated at reflux for 1 hour. At the end of this time, the methanol is removed, the residue diluted with additional water, and acidified to pH=4 with hydrochloric acid. The resulting precipitate is collected by filtration, washed with cold water, and dried.
