EXAMPLE - 25 g 5-Bromo-indole, 9.2 g 2-bromo-benzaldehyde and 180 ml methanol were added to three-necked flask with reflux tube, stirred at 80 degrees C for 22 hours, cooled to room temperature, solvent distillation was carried out and dried. 29 g Red solid as intermediate component, 5.3 g iodine and 87 ml acetonitrile were added, refluxed for 22 hours, cooled, filtered and dried. 4 g White solid and 8.8 g tetrabutylammonium hydroxide methanol solution were added, stirred at 120 degrees C for 48 hours, cooled, filtered and dried, to obtain greenish yellow compound. 1 g Greenish yellow compound, 441 mg phenylboronic acid, 103 mg tetrakis(triphenylphosphine)palladium, 7 ml toluene and 3 ml ethanol were added, stirred at room temperature, sodium carbonate aqueous solution was added, cooled, stirred at 90 degrees C for 14 hours, organic layer was washed with water, anhydrous magnesium sulfate was added and dried. The obtained yellowish green solid was dissolved in tetrahydrofuran, and methanol was poured, stirred at room temperature, filtered for 4 times and dried, to obtain 12,27-diphenyl-9,24-diazanonacyclo(15.13.1.12,9.03,8.010,15.018,23.024,31.025,30.016,32)dotriaconta-1,3(8),4,6,10,12,14,16(32),17(31),18(23),19,21,25(30),26,28-pentadecaene.
