2-bromo-3-pyridinol (230 mg) and potassium carbonate (216 mg) was dissolved in methylethylketone (10 ml) and reacted for 30 minutes. Then, (S)-3-bromo-2-methyl-1-propanol (0.21 ml) was added to the solution and refluxed for 3 hours at 100° C. Potassium carbonate was filtered out and separated by flash chromatography under a silica gel phase (ethyl acetate:normal hexane=1:1). As a result, (S)-3-(2-bromopyridine-3-yloxy)-2-methyl-1-propanol (260 mg, yield: 80%) was obtained.
