실험 절차

To 7.3 g (20.2) 5-[4-(Allyl-methyl-amino)-butoxy]-2,3-dihydro-indole-1-carboxylic acid tert-butyl ester in 15 ml CH2Cl2, 10 ml trifluoro acetic acid were added at 0° C. The mixture was stirred at reflux for 3 h and was concentrated in vacuo. Water and 2M NaOH were added and the inorganic phase was extracted with ether. The combined organic phases were washed with water and dried over Na2SO4. Evaporation yielded 5.2 g (98%) Allyl-[4-(2,3-dihydro-1H-indol-5-yloxy)-butyl]-methyl-amine as orange oil, MS: 261 (MH+)
