To a solution of 2.14 g of 1-(3,5-dichloro-4-pyridinyl)-1H-pyrrole-2-carbaldehyde in 10 ml of N,N-dimethylformamide was added 1.7 g of N-bromosuccinimide. The mixture was stirred at room temperature for 2 hours. Water was poured into the reaction mixture, and a deposited precipitate was collected by filtration to obtain 2.9 g of 4-bromo-1-(3,5-dichloro-4-pyridinyl)-1H-pyrrole-2-carbaldehyde of the formula:
