Procedure

The reaction was carried out according to the same procedure as described in Example 50 except that 5-trifluoromethyl-3-benzoylaminoisoxazole (0.8738 g, 3.41 mmole), 36% hydrochloric acid (0.87 g, 8.53 mmole) and ethylene glycol (3.4 ml) were used. The product was then purified by column chromatography on silica gel to give the title compound. Yield: 0.3686 g (75.7%). The structure of this product was confirmed by NMR.
