Procedure

A mixture of (5-Bromo-pyridin-2-yl)-methanol (60 mg, 0.32 mmol) in dichloromethane (2 ml) was cooled in as ice bath. To the mixture was then added triethylamine (0.13 mL, 0.96 mmol) followed by methanesulfonyl chloride (0.05 mL, 0.64 mmol). The reaction mixture was stirred at room temperature for 2 hours. To the reaction mixture was added saturated aqueous sodium bicarbonate (5 mL). The organic phase was separated and the aqueous phase extracted further with dichloromethane (2×5 mL). The combined organic phase was washed with brine, dried over sodium sulfate and concentrated to give the product as a pale brown oil.
