실험 절차

To a mixture of iodobenzene (204 mg, 1 mmol), sodium azide (130 mg, 2 mmol), sodium carbonate (53 mg, 0.5 mmol), CuI (19 mg, 0.1 mmol), sodium ascorbate (20 mg) and N,N′-dimethylethylenediamine (18 ul, 0.2 mmol) in EtOH (1.5 ml) and water (0.5 ml) were added 5-((trimethylsilyl)ethynyl)indolin-2-one (115 mg, 0.5 mmol), and stirred at 80° C. for 2 h. After cooling to ambient temp, EtOH was removed under reduced pressure. The residue was suspended in EtOH and stirred for 1 h at rt and filtered. The filtrate was washed with water and hexane and dried under vacuo to give 5-(1-phenyl-1H-1,2,3-triazol-4-yl)indolin-2-one (106 mg).
