Procedure

The reaction was carried out according to the same procedure as described in Example 50 except that 5-trifluoromethyl-3-pivaloylaminoisoxazole (0.7553 g, 3.20 mmole), 36% hydrochloric acid (0.81 g, 8.00 mmole) and ehtylene glycol (3.2 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.
