Reaction Steps

Intermediate 9 (3,5-difluoro-2-pyridinyl)methanol (114 mg, 0.786 mmol) was dissolved in DCM (anh) (6 mL) at 0° C. 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, 78% yield). 1H NMR (400 MHz, DMSO-d6) δ ppm: 1H NMR (300 MHz, DMSO-d6) δ 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+).
