Reaction Steps

To a 500 mL 3-neck round bottom flask was added o-toluidine (3.60 g, 33.6 mmol) and 150 mL toluene. The solution was cooled in an ice bath under nitrogen. Trimethylaluminum (2.0 M in toluene, 23.51 ml, 47.0 mmol) was added dropwise via dropping funnel. The reaction mixture was stirred at room temperature for 2 hours. Next, 3-iodobenzonitrile (10 g, 43.7 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 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. The solid was triturated with hexane, filtered, washed with hexane (7.77 g, 69%).
