반응 단계
Tert-butyldimethylsilyl trifluoromethanesulfonate (1.174 ml, 5.11 mmol) was added to 2,6-lutidine (0.743 ml, 6.38 mmol) and (5-bromopyridin-3-yl)methanol (800 mg, 4.25 mmol) stirred in CH2Cl2 (10 ml) cooled to 0° C. and the mixture was stirred at 0° C. for 1 h. Saturated aqueous sodium hydrogen carbonate was added to the reaction mixture and the mixture was extracted with ethyl acetate. The combined organic fractions were dried (Na2SO4), filtered and the solvent was evaporated under reduced pressure. The residue was purified by column chromatography to provide 3-bromo-5-({[tertbutyl(dimethyl)silyl]oxy}methyl)pyridine: MS: cal'd 325 (MNa+), exp 325 (MNa+).
