Procedure

Phosphorous pentoxide (2.02 g, 14.20 mmol) suspended in 1,2-dichlorobenzene (60 mL) was added to a mixture of 2-phenyl-furan (23) (500 mg, 2.84 mmol) and 3-bromophenylacetic acid (24) (1.34 g, 6.25 mmol). The reaction mixture was heated to 80° C. for 2 hours and then cooled to ambient temperature. DCM was added, the organic layer washed with water and partially reduced in vacuo. The crude product was purified by Flash Master Jones Chromatography using a 50 g silica cartridge and first eluting with heptane to remove excess 1,2-dichlorobenzene, then 5-10% EtOAc in heptane to give the title compound. Yield: 278 mg, 38%; LC-MS tr 1.73 min; HPLC Purity: 100%; MS (ES+) m/z 341, 343 (M+H)
