A mixture of Methyl 2-bromo-5-nitrobenzoate (0.60 g, 2.3 mmol), allyl tri-n-butyltin (0.92 g, 2.8 mmol), lithium chloride (0.29 g, 6.9 mmol), and palladium tetrakis (0.13 g, 0.12 mmol) was heated to reflux for 16 hours in toluene. TLC showed formation of the desired product. The reaction was diluted with EtOAc, washed with brine, and separated. The organic layer was dried over sodium sulfate, filtered and concentrated under reduced pressure. The residue was purified by silica gel chromatography to obtain the title compound.
