実験手順

2.45 g (6.8 mmol) 5-[5-(Allyl-methyl-amino)-pentyl]-2,3-dihydro-indole-1-carboxylic acid tert-butyl ester in 5 ml CH2Cl2 were treated with 4 ml TFA at 0° C. The solution was stirred at RT for 0.5 h, and at 40° C. for 1 h. The solution was concentrated and the residue was dissolved in ether and water. 2M NaOH was added and the inorganic phase was extracted with ether. The combined organic phases were washed with water and dried over Na2SO4 to yield 1.65 g (94%) Allyl-[5-(2,3-dihydro-1H-indol-5-yl)-pentyl]-methyl-amine as light yellow oil, MS: 259 (MH+).
