To a solution of 2.95 g of 1-(3-chloro-4-pyridinyl)-1H-pyrrole-2-carbaldehyde in 20 ml of N,N-dimethylformamide was added 2.66 g of N-bromosuccinimide. The resulting mixture was stirred at room temperature for 10 hours. Water was poured into the reaction mixture, and a deposited precipitate was collected by filtration to obtain 1.2 g of 4-bromo-1-(3-chloro-4-pyridinyl)-1H-pyrrole-2-carbaldehyde of the formula:
