YieldReaction ConditionsOperation in experiment
45% With cesium fluoride In dimethyl sulfoxide at 90℃; for 0.5 h; General procedure: To asolution of 3-bromo-2,6-dichloropyridine (4.70 g, 20.7 mmol) in DMSO (103 ml)was added cesium fluoride (12.6 g, 82.9 mmol) at room temperature. The mixturewas stirred at 80 °C under air for 8 h. The mixture was poured into water atroom temperature and extracted with Et2O. The organic layer wasseparated, washed with water and brine, dried over Na2SO4and concentrated in vacuo. (400 Torr, 40 °C). The residue was purified bycolumn chromatography (silica gel, eluted with EtOAc in hexane) to give 3-bromo-2,6-difluoropyridine (3B) (2.58 g, 64percent) as colorless oil. 1H NMR (CDCl3)δ: 6.79 1H,dd, J = 8.3, 3.0 Hz), 8.03 (1H, ddd, J = 8.4, 8.4 7.0 Hz). 19F NMR(CDCl3) δ: -69.3 Hz, -63.8 Hz.?The compound 4B-8B were prepared in a manner similarto that described for 3B.
