Reaction Steps
Add (bis(2-methoxyethyl)amino)sulfur trifluoride (2.05; mL, 11.11; mmol) dropwise to a cooled solution of 2-(6-bromo-pyridin-2-yl)-propan-2-ol (2; g, 9.26 mmol) in dichloromethane (46.3; mL) at −78° C. Upon addition, warm to room temperature and stir overnight. Add a saturated aqueous solution of sodium bicarbonate and stir until gas evolution stops. Filter through a 50; mL hydrophobic IST Phase Separator Frit®, concentrate and purify by silica gel chromatography, gradient eluting from 3:97; to 5:95; and then to 10:90; using dichloromethane:iso-hexane to give the title compound as a colorless liquid (5.13; g, 71%). 1H NMR (CDCl3) δ 1.66; (s, 3H), 1.73; (s, 3H), 7.37; (dd, 2H), 7.53; (m, 2H). 19F NMR (CDCl3) δ-143.37; (s, 1F).
