3,6-difluoro-N-(3-fluorobenzyl)pyridine-2-amine (0.5209 g, 2.19 mmol), was dissolved in anhydrous MeOH (6.6 mL) and placed under argon. This mixture then was treated with sodium methoxide (0.500 mL, 0.473 g, 2.19 mmol, 25% in MeOH) by slow addition. The resulting mixture was then heated in the microwave at 150° C. for four 30 min. The reaction mixture was then poured into brine (25 mL). This mixture was extracted with EtOAc (3×25 mL), the combined extracts were washed with brine (1×25 mL) and dried (Na2SO4). After filtration the solvent removed in vacuo. The resulting residue was subjected to silica gel column chromatography. Elution using 100 hexanes to 25 EtOAc/75 hexanes afforded 0.3408 g (62%) of 3-fluoro-N-(3-fluorobenzyl)-6-methoxypyridin-2-amine. LCMS (m/z): 251.1 (MH+), retention time=1.07 min.
