The synthetic route is as follows., Quality Control of 1-Bromo-4-chloro-2-fluorobenzene
General procedure: (2-Bromo-5-chloro-phenyl)hydrazine (6) A 250 mLround-bottom flask was charged with 1-bromo-4-chloro-2-fluoro-benzene (8.5 mL,68.0 mmol), hydrazine monohydrate (13 mL, 270 mmol) and dimethylsulfoxide (25mL) and the solution was stirred at 70 C for 3 days. The reaction was then cooled to room temperature and water (200 mL) was added. The precipitate was collected by filtration and dried under vacuum for 16 hours to give (2-bromo-5-chloro-phenyl)hydrazine (14.5g, 65 mmol, 96% yield) as a white solid. LCMS ES+ m/z = 221.0 [M+H]+.
