Embodiment 1
[0050] Preparation of Intermediate B:
[0051] Put 57.2g (148.9mmol) of 5,6-dinitro-1,4-dibromobenzothiadiazole, 88.3g (305.2mmol) of N,N-diphenyl-4-aminophenylboronic acid and 725.0g of THF into three ports bottle, add 61.6g (446.7mmol) of potassium carbonate, 190.0g of water, and pass nitrogen gas for 20min, then add 0.333g (1.49mmol) of palladium acetate and 1.309g (2.98mmol) of CXA·HBr to the system, reflux reaction for 5hr, TLC detection After the reaction was complete, the solvent was removed, suction filtered, and the powder was dissolved in THF, followed by column chromatography to obtain 80.6 g (113.2 mmol) of Intermediate B with a yield of 76% and a HPLC purity of 97.8%. Using HPLC-MS to identify the compound, formula C 42 h 28 N 6 o 4 S, detection value [M+1] + =713.58, calculated value 712.77.
[0052] Preparation of Intermediate C:
[0053] Put 80.6g (113.2mmol) of intermediate B, 320.0gTHF, 160.0g methanol, 4.03gPd / C (5% effective content) into the autocla...
