Embodiment 1
[0232] Embodiment 1: the synthesis of compound S1
[0233]
[0234] Step 1: Synthesis of compound 3a
[0235] Compound 1a (5 g, 46.3 mmol), compound 2a (5.3 g, 46.3 mmol) and TEA (13 mL, 92.6 mmol) were dissolved in 1,4-dioxane and stirred at room temperature for 3 h. After the reaction of the raw materials is complete, the precipitated solid is suction-filtered, and the filter cake is washed three times with 1,4-dioxane. Dissolve the filter cake in 25mL of acetic acid, add 10mL of concentrated hydrochloric acid, and heat to reflux for 2h. The volatile substances were distilled off under reduced pressure, and then the resulting solid was suspended in 45 mL of acetone while it was hot, stirred, cooled to room temperature, filtered with suction, washed with acetone three times, and the filter cake was vacuum-dried to obtain compound 3a (5.6 g, 60%). 1 H NMR (500MHz, DMSO-d 6 )δ12.03(s,1H),7.54–7.48(m,1H),7.46–7.40(m,1H),7.19–7.08(m,2H),2.69(t,J=6.4Hz,2H),2.43 (t,J=7.0Hz,2...
