(3-Allyloxy-pyridin-2-yl)-methanol (34 g, 205.8 mmol) is dissolved in dichloromethane (340 mL) under nitrogen and triethylamine (34.4 mL, 247 mmol) is added at 22° C. The mixture is warmed to room temperature in a water bath and methanesulfonyl chloride (16.7 mL, 216 mmol) is added keeping the temperature below 30° C. The reaction is allowed to stir overnight at room temperature. Water (500 mL is added and the mixture stirred for 10 min. The organic portion is separated and washed with a solution of saturated NaHCO3 (100 mL). The organic portion is dried over sodium sulfate, filtered, and the solvent evaporated. The resulting residue is dried under vacuum to constant weight to afford the title compound (29 g, 79%). LC-ES/MS m/z: 184.6 [M+H]+.
