Reaction Steps
A mixture of 2-fluoro-4-iodopyridine (2 g, 8.97 mmol), diethyl amine (2.77 ml, 26.9 mmol, 3 eq) and K2CO3 (2.48 g, 17.94 mmol, 2 eq) in DMF (20 mL) is stirred for 18 h at 100° C., allowed to cool to rt, diluted with EtOAc/H2O and extracted with EtOAc. The organic phase is washed with H2O and brine, dried (Na2SO4), filtered and concentrated. The residue purified by silica gel column chromatography (Hex/Et2O, 98:2) to afford 2.3 g of the title compound as a yellow oil: ESI-MS: 277.1 [M+H]+; TLC: Rf=0.52 (Hex/Et2O, 98:2).
