Procedure

The above general procedure was followed using 4-chlorobenzonitrile (137 mg, 1.00 mmol) and N-methylaniline (107 mg, 1.00 mmol) with 1 mol % Pd(dba)2 and 0.8 mol % tri-t-butylphosphine in 1.0 mL of toluene. After 12 hours, the reaction mixture was adsorbed onto silica gel and chromatographed with 10% ethyl acetate/hexanes to give 191 mg (92%) of N-(4-cyanophenyl)-N-methylaniline.
