Embodiment 1
[0081] First, under nitrogen protection, 3-bromobenzene-1,2-dione and 10-phenoxazine were added to dried toluene, and a trace amount of palladium acetate was added as a catalyst, and then an appropriate amount of tri-tert-butyl was added. base phosphorus and cesium carbonate, the resulting mixed solution is heated to 80-120° C., and stirred for 12-36 hours to complete the reaction. Preferably, the resulting mixed solution is heated to 110°C and stirred for 24 hours to complete the reaction.
[0082] After the reaction is completed, it is cooled to room temperature, the organic phase is washed five times with water first, then once with saturated sodium chloride solution, and then dried with anhydrous magnesium sulfate, and then the solvent in the organic phase is removed, and the obtained residue is passed through two processes. Subsequent recrystallization and purification obtain an intermediate having the structure represented by formula I-1.

Embodiment 2
[0088] First, under nitrogen protection, 3-bromobenzene-1,2-dione and 10-phenoxazine were added to dried toluene, and a trace amount of palladium acetate was added as a catalyst, and then an appropriate amount of tri-tert-butyl was added. base phosphorus and cesium carbonate, the resulting mixed solution is heated to 80-120° C., and stirred for 12-36 hours to complete the reaction. Preferably, the resulting mixed solution is heated to 90°C and stirred for 24 hours to complete the reaction.
[0089] After the reaction is completed, it is cooled to room temperature, the organic phase is washed five times with water first, then once with saturated sodium chloride solution, and then dried with anhydrous magnesium sulfate, and then the solvent in the organic phase is removed, and the obtained residue is passed through two processes. Subsequent recrystallization and purification obtain an intermediate having the structure represented by formula I-1.

Embodiment 3
[0095] First, under nitrogen protection, add 3-bromobenzene-1,2-dione and 10-phenothiazine to a mixture of dioxane and water, add a trace amount of palladium acetate as a catalyst, and then add an appropriate amount of of tri-tert-butylphosphorus and potassium carbonate, the resulting mixed solution is heated to 80-120° C., and stirred for 12-36 hours to complete the reaction. Preferably, the resulting mixed solution is heated to 90°C and stirred for 24 hours to complete the reaction.
[0096] After the reaction is completed, it is cooled to room temperature, the organic phase is washed five times with water first, then once with saturated sodium chloride solution, and then dried with anhydrous magnesium sulfate, and then the solvent in the organic phase is removed, and the obtained residue is passed through two processes. Subsequent recrystallization and purification yields an intermediate having the structure represented by formula I-2.
[0097] Then, the intermediate and 4...
