After mixing 15.0 g of 4-chloro-3-nitrobenzotrifluoride, 11.3 g of 5-t-butyl-3-hydroxyisoxazole, 11.0 g of potassium carbonate, and 80 ml of dimethyl sulfoxide, the mixture was reacted for 4 hours at 80° C. After cooling, the reaction mixture obtained was poured into water to deposit crystals which were then recovered by filtration and recrystallized from a mixture of water and methanol to provide 10.0 g of the desired compound with a yield of 45.5%. The melting point thereof was 116° to 117° C.
