Embodiment 1
[0049]
[0050] Step 1: Compound a 1 Synthesis,
[0051] Weigh and dissolve sodium azide (8.7g, 0.13mol) in 35mL of DMSO, heat and stir, dissolve phenylnitroalkene compound (16.63g, 0.11mol) in 30mL of DMSO, and slowly drop into the stack with a constant pressure dropping funnel. In the sodium nitride solution, one drop is added dropwise at a rate of 3 seconds, and the reaction temperature is 80°C. After the dropwise addition is complete, stop heating and continue stirring, and cool to room temperature; add ammonium chloride solution to the mixed solution, extract with ethyl acetate, extract the organic phase, wash the organic layer with saturated brine again, and then wash with anhydrous sulfuric acid The organic layer was dried over sodium, filtered, and concentrated under reduced pressure to obtain a yellow-brown solid. Finally, the obtained product was washed with dichloromethane in a small amount and several times to obtain about 14.51 g of a white solid with a yield...
