Procedure

To a solution of 0.5 g of 1-(2-pyrimidinyl)-1H-pyrrole-2-carbaldehyde in 10 ml of N,N-dimethylformamide was added 0.6 g of N-bromosuccinimide. The resulting mixture was stirred at room temperature for 1 hour. Water was poured into the reaction mixture, and the mixture was extracted with ethyl acetate two times. The organic layers were combined, washed successively with water and an aqueous saturated sodium chloride solution, dried over anhydrous sodium sulfate, and concentrated under reduced pressure. The resulting residue was subjected to silica gel chromatography to obtain 0.43 g of 5-bromo-1-(2-pyrimidinyl)-1H-pyrrole-2-carbaldehyde of the formula:
