실험 절차

To a solution of 5-iodoindolin-2-one (518 mg, 2 mmol), TEA (3 ml) and CuI (38 mg) in DMF (3 ml) was added to PdCl2(PPh3)2 (70 mg). The mixture was cooled to 0° C. and a solution of TMS-acetylene (1 ml). The mixture was maintained same temperature for 3 h, then warmed to rt. After stirring for overnight, the reaction mixture was concentrated in vacuo. The residue was purified by silica gel column chromatography to give 5-((trimethylsilyl)ethynyl)indolin-2-one (451 mg).
