The reaction was quenched with saturated aqueous ammonium chloride (5 mL) and filtered through diatomaceous earth to remove solids. The filtrate was evaporated and the resultant white solid was dissolved in ethyl acetate and water. The aqueous layer was extracted with ethyl acetate (5*30 mL) and the combined extracts were dried over anhydrous sodium sulfate. Solvent removal provided 3.78 g (93percent) of the titled product as a pale yellow oil: IR (CHCl3, cm-1) 3607, 3439, 3019, 1607, 1576, 1451, 1416, 1312, 1257, 1218, 1209, 1167, 1105, 1053, 857, 803; 1 H NMR (300 MHz, CDCl3) delta8.38 (m, 1H), 7.39 (m, 1H), 7.26 (m, 1H), 4.83 (s, 2H), 3.73 (br s, 1H); MS (FD) m/e 127 (M+);

N,N-diethylethanamine (ALDRICH, 0.131 mL, 0.943 mmol) and methanesulfonyl chloride (ALDRICH, 0.067 mL, 0.864 mmol) were added. Reaction mixture was stirred at 0° C. for 1 h 30 min. Crude of reaction was partitioned between water and DCM, aqueous layer was extracted with DCM (2*10 mL). Organic layers were dried over MgSO4 (anh) and filtered. Solvent was eliminated to yield title compound (3,5-difluoro-2-pyridinyl)methyl methanesulfonate (137 mg, 0.614 mmol, 78percent yield). 1H NMR (400 MHz, DMSO-d6) delta ppm: 1H NMR (300 MHz, DMSO-d6) delta ppm: 8.58 (d, 1H), 8.06-8.11 (m, 1H), 5.36 (d, 2H), 3.27 (s, 3H). [ES+MS] m/z 224 (MH+). Intermediates 19-21 were prepared by methods analogous to that described for Intermediate 18 but replacing the alcohol ((3,5-difluoro-2-pyridinyl)methanol) with that indicated in Table 2. Reaction times varied from 1 h to 4 h.
With triethylamine; In tetrahydrofuran; at 0℃; for 2h; To a solution of <strong>[31181-79-0](3-fluoropyridin-2-yl)methanol</strong> (230 mg) and triethylamine (74 mg) in THF (5 mL) was added methanesulfonyl chloride (71 mg) at 0°C, and the reaction mixture was stirred at 0°C for 2 hr. The reaction mixture was concentrated under reduced pressure, a saturated aqueous sodium hydrogen carbonate solution was added, and the mixture was extracted with ethyl acetate. The extract was washed with saturated brine, and dried over magnesium sulfate. The solvent was evaporated under reduced pressure to give the title compound. MS (ESI+) : [M+H]+206.2.
