3-Bromo-4-methoxybenzaldehyde is formed by the solvent-free bromination of 4-methoxybenzaldehyde using 1,3-di-n-butylimidazolium tribromide, as a brominating reagent. | [Synthesis]
(2) In a 4000 mL three-necked flask protected by passing nitrogen, 740.7 g of 3-bromo-4-hydroxybenzaldehyde, 2000 g of N,N-dimethylformamide and 558.0 g of potassium carbonate were added. The reaction system was cooled to 0~5 °C and 775 g of iodomethane was added dropwise slowly. After the dropwise addition, the reaction solution was concentrated and poured into ice water to precipitate a solid. After filtration and recrystallization, a white crystalline product 3-bromo-4-methoxybenzaldehyde was obtained as 752.7 g, yield 95.0%. | [References]
