56%	With bromine; acetic acid In chloroform at 50℃; for 16h;	4.3.17. 4,5-Dibromo-1H-pyrrole-2-carbaldehyde 8n³⁷ Pyrrole-2-carboxaldehyde (951 mg, 10.0 mmol), was dissolved in chloroform (30 mL) and glacial acetic acid (4.5 mL). Bromine (1.02 mL, 19.9 mmol) was slowly added at room temperature to the resulting cloudy solution and, once addition was complete, the reaction mixture was heated at 50 °C for 16 h. After cooling to room temperature the reaction mixture was quenched with NaHCO3 (150 mL of a saturated aqueous solution) and extracted with Et2O (50 mL×4). The combined organic layer was dried over MgSO4, filtered and the solvent was removed in vacuo. The crude product crystallized (EtOAc/pet. ether) affording 8n as pale pink powder (1.42 g, 56%).
