Procedure

A mixture of methyl 6-(bromomethyl)picolinate (0.264 g; 1.15 mmol), 3-fluorophenylboronic acid (0.190 g; 1.31 mmol), tetrakis(triphenylphosphine)palladium(0) (0.066 g; 0.057 mmol) and sodium carbonate (0.244 g; 2.30 mmol) in the mixture of water (1 mL) and 1,2-dimethoxyethane (3 mL) was heated at 130° C. in a microwave oven for 20 minutes. The reaction mixture was diluted with ethyl acetate, and washed with water. The organic layer was concentrated under reduced pressure and the residue was purified by flash chromatography on silica gel (eluent 0 to 6% of ethyl acetate in dichloromethane) to give 0.0524 g (19%) of methyl 6-(3-fluorobenzyl)picolinate as an oily residue.
