(5-Bromo-3-fluoropyridin-2-yl)methanol (0.20 g, 0.99 mmol) was dissolved in dichloromethane (5 mL), cooled to 0° C. and treated with triethylamine (0.15 mL, 1.1 mmol, 1.1 equiv) and methanesulfonyl chloride (0.085 mL, 1.1 mmol, 1.1 equiv). After 15 minutes, the mixture was diluted with dichloromethane (100 mL) and washed once with sodium bicarbonate (20 mL, aqueous saturated) and brine (50 mL), dried with sodium sulfate, filtered and concentrated in vacuo, providing the titled compound.
