실험 절차

4.8 g (13 mmol) 5-(4-Bromo-butoxy)-indole-1-carboxylic acid tert-butyl ester in 5 ml DMF were treated with 5 ml (48.1 mmol) diethylamine at 50° C. for 5 h. The solution was concentrated and extracted with ether and water. The combined organic phases were dried over Na2SO4 to yield 3.95 g (85%) 5-(4-Diethylamino-butoxy)-indole-1-carboxylic acid tert-butyl ester as yellow oil, MS: 361 (MH+).
