3,4-Difluorotoluene Use and Manufacturing

General procedure: A glass reactor equipped with a Teflon-lined magnetic stir bar and connected to a gas-washing bottle was charged with C6H5R (0.95–1.14 mmol), MeCN (1–2.5 mL per mmol of C6H5R), and BF3 · Et2O (1.3–1.6 mmol per mmol of C6H5R). The solution was stirred for 10–15 min at –25°C, and XeF2 (1.2–1.3 mmol per mmol of C6H5R) was added in portions. The mixture was allowed to warm up to 22°C over a period of 1 h and stirred for 40–60 min more, hexafluorobenzene (internal standard) was added, and a sample was withdrawn for 19F NMR analysis (procedure B). The mixture was treated with a saturated aqueous solution of NaHCO3 and extracted with methylene chloride (1–2 mL). The extract was dried over MgSO4 and analyzed by 19F and GC/MS (procedure C). The main products are given in table, and the others are listed below (GC/MS data).[2-(5, 6-Difluoro-1H-indol-3-yl)-cyclopropylmethyl]-dimethyl-amine
