The above ether (3.6 g, 13.6 mmol) was dissolved in acetic acid (40 ml) and 48% hydrobromic acid (20 ml) was added. After 7 days the mixture was diluted with water (200 ml) and extracted with benzene (100 ml). The organic phase was dried (MgSO4), filtered and the solvent was evaporated in vacuo to give 3.8 g of crude 5-(1-methyl-2-bromoethylidene)-10,11-dihydro-5H-dibenzo[a,d]cycloheptene.
