| | 6-Bromoveratraldehyde Usage And Synthesis |
| Chemical Properties | WHITE TO LIGHT YELLOW CRYSTALS OR POWDER | | Uses | 6-Bromoveratraldehyde was used in the preparation of benzylchromenylamines. | | Synthesis | (1) Add 529 g of bromine dropwise to 500 g of 3,4-dimethoxybenzaldehyde dissolved in 2.5 L of methanol at room temperature (cooled if necessary) within 1 hour and stir the reaction mixture at the same temperature for 3 hours. Subsequently, 2.5 L of water was slowly added dropwise to the reaction solution to induce precipitation of crystals. A 20% aqueous sodium hydroxide solution was added to the crystal suspension at room temperature and the pH was adjusted to about 9-10, followed by cooling. The precipitated crystals were collected by filtration, washed with water and dried at 50 °C for 12 h. 718.78 g of 6-bromo-3,4-dimethoxybenzaldehyde was finally obtained (yield: 98%). | | References | [1] Heterocycles, 2015, vol. 90, # 1, p. 730 - 739
