Versuchsvorschrift
175 g of (0.732 mol) 1-benzylhexahydroazepin-4-one hydrochloride IV are dissolved in 500 mL acetic acid. Upon addition of 100 mL of a saturated solution (30%) of hydrobromic acid in acetic acid, 37 mL (0.732 mol) of bromine are added dropwise at room temperature and with efficient stirring, whereby the brown color of bromine disappears.
