Procedure

To a 500 mL 3-neck round bottom flask was added aniline (5.38 g, 57.8 mmol) and 150 mL toluene. The solution was cooled in an ice bath under nitrogen. Next trimethylaluminum solution in toluene was added dropwise via dropping funnel (2.0 M, 40.4 mL, 81 mmol) and the reaction mixture was stirred at room temperature for 2 h. Next 3-methoxybenzonitrile (10 g, 75 mmol) in 50 mL toluene was added and the reaction mixture was heated to 70° C. overnight under nitrogen. The reaction mixture was cooled in an ice bath and then poured onto a stirring slurry of silica gel in 2:1 dichloromethane/methanol. The silica gel was filtered off and washed with dichloromethane and methanol. The filtrate was evaporated leaving a solid which was triturated with hexane, filtered, and washed with more hexane and dried to give desired product (7.81 g, 60%).
