Procedure

4-Trifluoromethanesulfonyloxy-7-[1-(tert-butoxycarbonyl)-5-(piperidinomethyl)indol-2-yl]isoindolinone (80.0 mg, 0.135 mmol) was dissolved in acetonitrile (4.8 mL), and the solution was added with tetrakis(triphenylphosphine)palladium (23.4 mg, 0.0203 mmol), copper iodide (10 mg, 0.054 mmol), tetrabutylammonium chloride (150 mg, 0.405 mmol), 3-butyn-1-ol (0.051 mL, 0.68 mmol) and triethylamine (0.96 mL, 0.70 mmol), followed by stirring at room temperature for 40.7 hours under argon atmosphere. The reaction mixture was added with water and extracted with ethyl acetate. The organic layer was washed with saturated brine and dried over anhydrous sodium sulfate. The solvent was evaporated under reduced pressure, and the residue was purified by preparative thin-layer chromatography (chloroform/methanol=5/1) to obtain 4-(4-hydroxy-1-butynyl)-7-[1-(tert-butoxycarbonyl)-5-(piperidino methyl)indol-2-yl]isoindolinone (35.5 mg, yield 51%).
