Participants

Reaction Steps

To 2-methyl-propan-1-ol (10 g, 0.41 mol) was added NaH (60%, 8.2 g, 0.204 mol) portionwise under a nitrogen atmosphere at room temperature over 10 minutes. The mixture was refluxed for 30 minutes. A solution of 5-bromo-2-fluoro-pyridine (24 g, 0.136 mol) in DMF (400 mL) was added dropwise and the mixture refluxed for 18 hours. The reaction mixture was then diluted with water (1 L) and extracted with EtOAc (3×500 mL). The combined organics were washed with brine (3×300 mL), dried over sodium sulfate, filtered and concentrated in vacuo. The crude residue obtained was purified by flash column chromatography eluting with petroleum ether to yield the title compound as a colourless oil (27 g).
