Reaction Steps

2-(Tributylstannyl)pyridine (11.2 g, 30.4 mmol) was dissolved in toluene (240 mL), methyl 4-bromo-2-fluorobenzoate (7.4 g, 33.4 mmol) and tetrakis(triphenyl-phosphine) Pd (1.75 g) were added thereto. The mixture was poured into water, extraction was carried out with ethyl acetate, the organic phase was dried and the solvent was evaporated. The residue was purified by column chromatography (silica gel, petroleum ether:ethyl acetate 50:1 to 10:1) to give methyl 2-fluoro-4-(pyridin-2-yl)benzoate (2.5 g, yield 35%). 1H-NMR (400 MHz, CDCl3) δ (ppm): 3.93 (s, 3H), 7.31-7.34 (m, 1H), 7.76-7.85 (m, 4H), 8.05 (t, J=7.6 Hz, 1H), 8.72-8.74 (m, 1H); LC-MS (ESI) m/z: 232 (M+1)+.
