A stirring solution of 4-((6-bromo-3-(difluoromethoxy)-2-methoxyphenoxy)methyl)benzamide (500 mg, 1.24 mmol) in dimethylformamide (10 mL) was purged with argon for 1 h, to this cesium carbonate (1.2 g, 3.73 mmol), tetrakis(triphenylphosphine) palladium(0) (72 mg, 0.06 mmol) and 4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-2,3-dihydro-1H-inden-1-one (641 mg, 2.48 mmol) was added and the resultant reaction mixture was heated to 80° C. for 16 h. The reaction mixture was cooled to RT and filtered through celite and the filtrate was concentrated under reduced pressure. The residue was purified by column chromatography (silica gel, 0-80% ethyl acetate in pet ether) to afford title compound as a solid (150 mg, 26.7%).
