Reaction Steps

Into a 16 by 100 mm vial sparged with argon was added 3-amino-5-bromobenzotrifluoride (1 g, 4.16 mmol), 2-pyrrolidinone (425 mg, 5 mmol), N,N′-dimethylethylenediamine (37 mg, 0.416 mmol), potassium carbonate (1.15 g, 8.33 mmol), copper(1)iodide (80 mg, 0.416 mmol), and toluene (1 mL). Vial capped, heated with stirring at 85° C. for 24 h. Reaction cooled to RT, solvent removed under reduced pressure, reconstituted in DCM and filtered through silica. Affords a gray solid. MS m/z=245 [M+H]+. Calc'd for C11H11F3N2O: 244.2
