Procedure

A mixture of 1-oxo-2,3-dihydro-1H-inden-4-yl trifluoromethanesulfonate (10.0 g, 35.7 mmol), 2,6-dimethylphenylboronic acid (6.96 g, 46.4 mmol), 2-(dicyclohexylphosphino)biphenyl (750 mg, 2.14 mmol), tris(dibenzylideneacetone)dipalladium(0) (1.31 mg, 1.43 mmol), tripotassium phosphate (15.2 g, 71.4 mmol) and toluene (200 mL) was heated under reflux under an argon atmosphere at 90° C. for 16 hr. After cooling the reaction mixture, the insoluble material was filtered off, and the filtrate was concentrated under reduced pressure. The residue was purified by silica gel column chromatography (5%-45% ethyl acetate/hexane) to give the title compound (7.21 g, yield 85%) as pale-yellow crystals.
