실험 절차
7-Bromoindole(0.37 g, 1.9 mmol) was dissolved in dry DMF. K2CO3 (0.52 g, 3.8 mmol) and methyliodide (0.13 mL, 2.08 mmol) were added. The reaction was stirred at room temperature for 5 days, after which H2O (20 mL) was added, the water phase was extracted with Et2O (3×20 mL), and the combined organic phases were washed with brine, dried (MgSO4), filtered and concentrated in vacuo. The crude product was purified by chromatography, eluent EtOAc:petroleum ether 1:20 to give 7-bromo-1-methylindole as a crystalline compound.
