Embodiment 1

[0050]

[0051]Dissolve the raw material (0.45g, 1mmol) with the structural formula (1-1) in 100ml of dichloromethane, add diisopropylethylamine (0.17ml, 1mmol) dropwise, and add tribromo Boronide (2.94ml.3mmol, 1M). Stir at room temperature for 24 hours. After the reaction, the color of the reaction solution is darkened and poured into water, extracted with dichloromethane, washed the organic layer with water, dried with anhydrous magnesium sulfate, filtered, and evaporated to obtain the primary product. Dissolve the obtained primary product in 100ml of toluene, add trimethylaluminum (1.08ml, 2.2mmol, 2M) at room temperature, react for 3 hours at room temperature, pour into water, extract with dichloromethane, wash the organic layer with water, anhydrous sulfuric acid Dry over magnesium, filter, and rotavap to give an intermediate product. The intermediate product was loaded into a column with a mixture of petroleum ether and dichloromethane (volume ratio of the mixture =...
