Embodiment 1
[0124] Embodiment 1: the synthesis of compound H31
[0125]
[0126] In the three-necked flask, under the protection of nitrogen, add 0.01mol raw material A, 0.012mol raw material B, 0.02mol sodium carbonate, mixed solvent (150ml toluene, 45ml H 2 O), then add 1×10 -4 mol tetrakis(triphenylphosphine)palladium Pd(pph 3 ) 4 , heated to 105°C, refluxed for 24 hours, sampling and spotting the plate, showing that no bromide remains, and the reaction is complete. Naturally cooled to room temperature, filtered, and the filtrate was subjected to vacuum rotary evaporation (-0.09MPa, 85°C), passed through a neutral silica gel column (silica gel 100-200 mesh, the eluent was chloroform:n-hexane=1:2 (volume ratio) ), to obtain intermediate M. Elemental analysis structure (molecular formula C 24 h 15 ClBrN): Theoretical C 66.61; H 3.49; Br 18.46; Cl 8.19; N 3.24; Found: C 66.57; H 3.46; MS: The theoretical value is 431.01, and the measured value is 431.24.
