Procedure
N-phenylphenanthren-9-amine (4.51 g, 16.74 mmol), 1,3-dibromobenzene (6.05 mL, 50.23 mmol), Pd2(dba)3 (307 mg, 0.355 mmol), tris-o-tolyphosphine (0.255 mL, 0.837 mmol), sodium tert-butoxide (3.2 g, 33.49 mmol) were put in a 250 mL two-neck flask and dissolved in toluene. The solution was refluxed and stirred for 12 hours. After completion of the reaction, the solution was extracted with DI water/methylenechloride and distilled under reduced pressure to remove the solvent. The resultant was columned with a solution of n-hexane and methylenechloride (7:1). The resultant was distilled under reduced pressure and re-crystallized such that the wax compound was obtained, (2.9 g, yield: 41%).
