| [General Description]
6-Bromo-2-hydroxy-3-methoxybenzaldehyde is a bromobenzaldehyde derivative. It participates in the synthesis of (±)-norannuradhapurine. Its crystals exhibit monoclinic crystal system and space group P21/n. | [Synthesis]
2-Acetoxy-3-methoxy-6-bromobenzaldehyde (48.2 g, 176.5 mmol) was used as starting material and dissolved in methanol (500 mL). Subsequently, 6 N hydrochloric acid (500 mL) was slowly added and the reaction mixture was stirred at room temperature overnight. Upon completion of the reaction, the product was separated by diafiltration. The filter cake was washed with petroleum ether (100 mL × 3) and subsequently dried under vacuum to afford the yellow solid product 6-bromo-2-hydroxy-3-methoxybenzaldehyde (40.4 g, 99% yield). | [References]
