Versuchsvorschrift

To a stirred solution of 2-amino-4-methoxybenzaldehyde (6 g, 39.7 mmol) in dichloromethane (100 mL) was added N-bromosuccinimide (7 g, 39.7 mmol). LCMS monitored the reaction until the starting material consumed completely. The reaction mixture was diluted with dichloromethane and water. The separated organic layer was dried sodium sulfate, filtered and concentrated to give the title compound (5 g, 56%) as a yellow solid. MS (ES+) C8H8BrNO2 requires: 229, 231. Found: 230, 232 [M+H]+.
