Reaction Steps

A solution of 5-(4-nitrophenyl)-1H-pyrazole (595 mmol) in N,N-dimethylformamide (1000 mL) was treated with N-bromosuccinimide (654 mmol). The reaction stirred for 30 min at room temperature and was poured into ice-water (1000 mL). Product precipitated out of solution, was filtered, washed with water (4×500 mL) and dried to provide the title product as an off-white powder (90%). ESMS [M+H]+: 269.2
