The reaction mixture was diluted with 100 ml of water, followed by 100 ml of 10% hydrochloric acid, and the resulting solution was washed with dichloromethane. The aqueous phase was basified with sodium bicarbonate and then it was extracted with dichloromethane. The combined extracts were dried using potassium carbonate and evaporated in vacuo to give 12.3 g (79%) of the title compound as a reddish oil.

70%		Aqueous hydrobromic acid (48%, 2.41 mL) was added to 4-fluoro-3-methoxyaniline (1.0 g, 7.1 mmol) in water (10 mL) and the resulting mixture was cooled to 0 C in an ice bath. A solution of sodium nitrite (538 mg, 7.8 mmol) in water (5 mL) was added dropwise during 15 min while maintaining the temperature between 0-5 0C. The resulting diazoniumsalt solution was added to a suspension of copper(I) bromide (1.12 g, 7.8 mmol) in water (5 mL) which had been pre-heated to 75 C. The mixture was shaken thoroughly, aqueous hydrobromic acid (48%, 12.07 mL) was added and the solution was stirred at ambient temperature for 16 h. Excess water was added and the product was extracted with diethyl ether and the combined organic extracts were washed with aqueous saturated sodium chloride, dried over magnesium sulfate, filtered and the solvent was evaporated in vacuo to give 1.02 g (70% yield) of the title compound.: 1H-NMR (DMSO-J6): delta 7.36 (dd, J= 7.78, 2.26 Hz, 1 H), 7.23-7.17 (m, 1 H), 7.14-7.09 (m, 1 H), 3.86 (s, 3 H); MS (EI) (m/z, %) 204,206 (100), 189,191 (23), 161,163 (45)

The resulting mixture was cooled to 0 C., and a solution of 11.2 g (0.162 mole) of sodium nitrite in 100 ml of water was added dropwise during 1 hour, with stirring, maintaining the temperature between 0 and 5 C. The solution of the diazonium salt thus obtained was then added to a suspension of 23.2 g (0.162 mole) of cuprous bromide in 100 ml of water which had been preheated to 75 C. The mixture was shaken thoroughly and then 251 ml of 48% hydrobromic acid was added. The resulting mixture was stirred overnight at room temperature and then it was diluted with an excess of water. The product was extracted into diethyl ether, and the extract was washed with saturated sodium chloride solution and dried (MgSO4). Evaporation of the dried ethereal solution in vacuo afforded a black liquid, which was distilled under reduced pressure. This afforded 23 g of the title compound as a yellow liquid, b.p. 82-85 C. (8 mm of Hg).
