Reaction Steps

Triethylamine (0.98 mL, 7.0 mmol) was added to a −5° C. solution of 4-trifluoromethylbenzoylacetonitrile (1.5 g, 7.0 mmol) in ethanol (15 mL) and the mixture was stirred for 20 minutes. A solution of ethyl 2-chloro-2-(hydroxyimino)acetate (1.06 g, 7.0 mmol) in ethanol (5 mL) was added to the reaction over 15 minutes. After stirring at room temperature for 72 hours, the cream-colored solid which formed was collected by filtration, washed with cold water and dried in vacuo to obtain ethyl 4-cyano-5-(4-(trifluoromethyl)phenyl)isoxazole-3-carboxylate (1.84 g, 5.93 mmol).
