With hydrogenchloride; hexafluorophosphoric acid; sodium nitrite; In water; at -10 - -5℃; for 0.5h; | 2-Bromo-1 -fluoro-3-methylbenzene; A 200 mL round bottom flask, equipped with a magnetic stirring bar, was charged with 2-bromo-3-methylaniline (12.2 g, 65.58 mmol), 113 mL of water, and 17.5 mL of cone. HCI. The mixture was briefly heated to dissolve the solids, then cooled to -10 0C. To the resulting suspension a solution of NaNO2 (5.06 g, 73.38 mmol) in 13 mL of water was added dropwise at -5 to -10 0C. Then 16.8 mL of 60% HPF6 in water (122.23 mmol) was added, and the resulting suspension was stirred for 30 min. The precipitate was collected by vacuum filtration, washed with ice-cold water (2x30 mL), then with an ice-cold MeOH/ether (16mL/64mL) mixture and dried under vacuum at room temperature for 20 h to give 20.46 g (91%) of diazonium salt. The dry salt was thermally decomposed in 5 g batches in a small (25 mL) vacuum distillation apparatus under vacuum (2 mm Hg), at 165-175 0C, with receiving flask cooled with a dry ice/acetone mixture. The collected fractions were combined to give 7.85 g of 2-bromo-1 -fluoro-3-methylbenzene as a colorless oil. 1H NMR (300 MHz, CDCI3): delta 7.16 (1H), 6.92-7.04 (2H), 2.43 (3H). |
