To a solution of 4-chloro-2-fluoro-1-iodobenzene (2.0 g, 7.8 mmol) in DMSO (10 mL) was added ethynyl(trimethyl)silane (1.14 g, 11.0 mmol), copper iodide (0.029 g, 0.15 mmol), bis(triphenylphosphine) palladium(II) chloride (0.218 g, 0.3 mmol) and TEA (1 mL). The reaction mass was stirred at RT for 4-5 h. The reaction mass quenched in water, passed through celite bed and extracted with ethyl acetate and concentrated to afford 1.0 g of desired product.
