Reaction Steps

A mixture of 4-bromo-3-nitrobenzaldehyde (1 g, 4.35 mmol) in dimethylformamide (10 mL) was added cuprous cyanide (584.8 mg, 6.53 mmol). The resultant solution was stirred at 160° C. for 5 hours. After cooling, a standard aqueous/EtOAc workup was followed. Purified by silica gel column chromatography to give product (430 mg, yield 56.1%).
