실험 절차
A solution of (5-bromo-pyridin-2-yl)-methanol (20.0 g, 106 mmol) in 150 mL of dichloromethane was cooled to 0° C. under nitrogen. Triethylamine (19.3 mL, 138 mmol) was added, followed by methanesulfonyl chloride (9.95 ml, 128 mmol). After 2.5 hours, the mixture was quenched with 50 mL of water and diluted with 100 mL of dichloromethane. The organic layer was washed with an additional 50 mL of water and then the aqueous layer was extracted with 100 mL of methylene chloride. The organic extracts were dried over sodium sulfate, filtered and concentrated to provide (5-bromopyridin-2-yl)methyl methanesulfonate as a red solid that gave a proton NMR spectra consistent with theory and a mass ion (ES+) of 268.1 for M+H+(81Br).
