Benzofuran boronic acid (0.289 mmol), 2-bromo-6-methoxyimidazo[1,2-a]pyridine (0.263 mmol), Pd(dppf)Cl2 (0.013 mmol) and K2CO3 (aq.) were stirred in DMF at 80° C. under argon for 1 h. The reaction mixture was allowed to cool to r.t. and brine was added. The reaction mixture was extracted with CH2Cl2 and the organic phase was filtered. The solvents were removed under reduced pressure and the residue purified by reverse phase HPLC to afford the title compound (0.5 mg). 1H NMR δ ppm 7.95 (s, 1 H) 7.67 (d, 1 H) 7.65-7.60 (m, 1 H) 7.58-7.51 (m, 2 H) 7.33-7.20 (m, 3 H) 7.03 (dd, 1 H) 3.86 (s, 3 H); MS m/z 265 (M+H).
