Procedure
After mixing 226 g of 4-chloro-3-nitrobenzotrifluoride, 129 g of 3-hydroxy-5-methylisoxazole, 336 g of sodium hydrogencarbonate, and 600 ml of dimethyl sulfoxide, the reaction was performed for 6 hours at 75° C. After the reaction was over, the reaction mixture obtained was poured into water, and crystals thus formed were purified by silica gel short column and recrystallized from a mixture of water and methanol to provide 176 g of the aforesaid compound with a yield of 61.1%. The melting point thereof was 122° C.
