(Nicodem: "2,5-Dimethoxybromobenzene Chloromethylation", Novel Discourse) for using the in situ preparation of bromine from KBr in a two phase system. It is more economic for KBr and very handy for the bromination of activated aromatics. But off course it is useless for the bromination of acid soluble compounds like phenylethylamines.(https://www.thevespiary.org/rhodium/Rhodium/hive/hiveboard/picproxie_imgs/djvu.gif)
Bubble chlorine through a saturated solution of sodium (or potassium) bromide. The bromide ions will be oxidised into bromine, some of which will further react with the chlorine to produce bromine monochloride.
Bromine monochloride boils at 5°C, and so if the sodium bromide solution is kept at about 10°C (in order to get the product into gas phase, whilst minimising evaporation of the bromine), the outgoing gas should consist of the product mixed with excess chlorine. This can then be seperated out by cooling the gas.

Since when is that a source?
Since the moderator who rated your post decided it was, quit whining :P
