実験手順
In 100 ml of dimethyl sulfoxide were dissolved 23.0 g of ethyl 4-chloro-3-nitrobenzoate and 17 g of 5-t-butyl-3-hydroxyisoxazole and after adding thereto 17 g of potassium carbonate, the reaction was performed for 8 hours at 75° C. After the reaction was over, the reaction mixture obtained was poured into cold diluted hydrochloric acid followed by stirring, whereby colorless crystals deposited immediately. The crystals were recovered by filtration and recrystallized from ethanol to provide 31.7 g of the desired compound with a yield of 94.8%. The melting point thereof was 88° C.
