Procedure

The above general procedure was followed using 4-chlorobenzonitrile (138 mg, 1.00 mmol) and diphenylamine (169 mg, 1.00 mmol) with 1 mol % Pd(dba)2 and 0.8 mol % tri-t-butylphosphine in 2.0 mL of toluene. After 5.5 hours, the reaction mixture was adsorbed onto silica gel and chromatographed with 50% toluene/hexanes to give 242 mg (90%) of N-(4-cyanophenyl)diphenylamine as a white solid.
