Reaction Steps
To a solution of 2-chloromethyl-6-fluoro-pyridine I-3c (1.43 g, 9.84 mmol) in H2O (22 mL) was added K2CO3 (1.77 g, 12.8 mmol). The reaction mixture was stirred overnight at reflux. The cooled aqueous mixture was first extracted with heptane (2×20 mL)and then ethyl acetate (2×50 mL). The ethyl acetate layers were combined, washed with brine, dried (Na2SO4), and concentrated to dryness. The crude residue was chromatographed over silica gel (15 g) using 2% methanol/methylene chloride with 0.5% NH4OH as the eluant to yield 518.7 mg of the title compound (I-3d) as a yellow oil.
