Reaction Steps

Lithium aluminum hydride (1.0M in THF) (Aldrich, St. Louis, Mo.; 12.98 mL, 12.98 mmol) was added to a solution of tert-butyl 2-(6-fluoropyridin-3-yl)-2-methylpropanoate (2.07 g, 8.65 mmol) in THF (34 mL) at 0° C. (gas evolution), and the resulting solution was stirred at 0° C. for 5 min. EtOAc (15 mL) was then added at 0° C. to quench excess lithium aluminum hydride, followed by 10% aqueous Na/K tartrate (150 mL). The resulting mixture was stirred at 25° C. for 10 min and then partitioned between EtOAc (200 mL) and water (50 mL). The organic layer was separated, and the aqueous layer was extracted with EtOAc (150 mL). The combined organic extracts were washed with brine (150 mL), dried over sodium sulfate, filtered, and concentrated in vacuo to provide 2-(6-fluoropyridin-3-yl)-2-methylpropan-1-ol (1.46 g, 8.63 mmol, 100% yield) as a colorless oil. 1H NMR (400 MHz, CDCl3) δ 8.22 (br. s., 1H), 7.78-7.84 (m, 1H), 6.89 (dd, J=8.6, 3.1 Hz, 1H), 3.63 (s, 2H), 1.36 (s, 6H). 19F NMR (377 MHz, CDCl3) δ −72.21 (br. s., 1F). m/z (ESI, +ve) 170.2 (M+H)+.
