Diisopropylaniline → HCID 178422447, compound

Participants

Reaction Steps

To a 250 mL 3-neck round bottom flask was added 2,6-diisopropylaniline (2.365 g, 13.34 mmol) and 70 mL toluene. The solution was cooled in an ice bath under nitrogen and trimethylaluminum (2.0 M in toluene, 9.34 mL, 18.68 mmol) was added dropwise via dropping funnel. The reaction mixture was stirred at room temperature for 2 hours. Next, 3-bromo-5-methylbenzonitrile (3.4 g, 17.34 mmol) in 30 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 was poured onto a stirring slurry of silica gel in 2:1 dichloromethane/methanol (v/v). The silica gel was filtered off and washed with dichloromethane and methanol. The filtrate was evaporated leaving a solid. Hexane was added to the solvent and the solid was filtered off and washed with hexane (2.92 g, 59%).
