실험 절차

Benzyl bromide (160 μl) and 1,8-diazabicyclo[5.4.0]undec-7-ene (201 μl) were added to a solution of 5-bromo-1H-indole-2-carboxylic acid (161 mg) in acetonitrile (3.5 ml) at room temperature, followed by stirring for 22.5 hours. The reaction solution was concentrated and separated by adding ethyl acetate and distilled water. The resulting organic layer was washed with brine and dried over anhydrous sodium sulfate. The solvent was evaporated under reduced pressure. The resulting residue was solidified from dichloromethane-hexane, collected by filtration and washed with hexane. This was dried under reduced pressure to give the title compound (189 mg).
