Neopentyl alcohol → 2-Fluoro-6-(neopentyloxy)pyridine

関与物質

反応手順

A solution of neopentyl alcohol (1.065 mL, 9.81 mmol) in DMSO (82 mL) was cooled to 0° C. NaH (60% in mineral oil; 0.490 g, 12.26 mmol) were added in one portion, the reaction mixture was warmed to rt and stirred for 20 minutes. 2,6-Difluoropyridine (0.941 mL, 8.175 mmol) was added and the reaction mixture was stirred at overnight. The reaction mixture was quenched with aqueous, saturated ammonium chloride solution, diluted with water and EtOAc. The organic layer was separated, washed with brine and dried over sodium sulfate. The solvent was removed under reduced pressure to afford 2-fluoro-6-(neopentyloxy)pyridine (1.48 g, 8.08 mmol) as a colorless liquid.
