Reaction Steps

Mixing 4-amino benzoic acid and lithium hydroxide in DMAc, then adding 3,5-dibromo-6H-anthra[1,9-cd]isoxazol-6-one into the mixture at about 40-60° C. Stirring the reaction mixture for up to 24 hours. Adding MTBE to the reaction mixture. Filtering the solid and drying to get 4-((3-bromo-6-oxo-6H-anthra[1,9-cd]isoxazol-5-yl)amino)benzoic acid (Intermediate 5).
