Versuchsvorschrift
4-Methoxy-2-methylaniline (9.30 ml, 72.9 mmol) in chloroform (250 ml ) at 0° C. was added a solution of bromine (3.76 ml, 72.9 mmol) in chloroform (60 ml) dropwise over ca. 3 h. The reaction mixture was concentrated, diluted with dichloromethane and concentrated, diluted again with diethyl ether and concentrated, and dried under high vacuum to give 18.5 g of 2-bromo-4-methoxy-6-methylaniline hydrobromide (85%). LC/MS (HPLC method 3): tR=1.395 min, 216.03(MH)+.
