Reaction Steps
To a solution of 1.5 g of 3-chloro-2-(2-formyl-1H-pyrrol-1-yl)pyridine in 20 ml of N,N-dimethylformamide, 1.3 g of N-bromosuccinimide was added. The mixture was stirred at room temperature for 3 hours. Water was poured into the reaction mixture, and a deposited precipitate was collected by filtration to obtain 1.9 g of 4-bromo-1-(3-chloro-2-pyridinyl)-1H-pyrrole-2-carbaldehyde of the formula:
