Procedure

A mixture of benzeneboronic acid (0.024 g; 0.195 mmol), N-(2-(5-bromo-1H-indol-3-yl)ethyl)-4-(3-fluorobenzyl)benzamide (0.080 g; 0.177 mmol), tetrakis(triphenylphosphine)palladium(0) (0.020; 0.017 mmol) and sodium carbonate (0.038 g; 0.355 mmol) in a mixture of DME (3 mL) and water (1 mL) was irradiated in the microwave oven at 130° C. for 20 minutes. The resulting solution was partitioned between water and ethyl acetate and the organic layer was concentrated under reduced pressure. The crude material was purified by flash chromatography on silica (eluent 20 to 100% ethyl acetate in heptane) and by preparative HPLC (method 2) to afford 0.013 g (16%) of the title compound as a white solid.
