実験手順
To 0.50 g (2.2 mmole) of 3-pentafluoroethyl-5-hydroxyisoxazole sodium salt were added dry acetonitrile (7 ml) and N-methyl-N-phenyl-2-bromoacetamide (0.55 g) and the resulting mixture was stirred at 60° C. for 24 hours. After completion of reaction, the reaction solution was evaporated under reduced pressure and to the residue was added water (80 ml), extracted with methylene chloride, treated with anhydrous sodium sulfate and concentrated under reduced pressure. The residue was purified by chromatography on silica gel to give 0.52 g of crystals. These crystals were recrystallized from n-hexane to give 0.48 g of the titled compound as colorless plates, yield 62.3%, m.p. 88.0-89.0° C.
