130 mg (0.5 mmol) Allyl-[5-(2,3-dihydro-1H-indol-5-yl)-pentyl]-methyl-amine in 0.5 ml dioxane were treated with 0.072 ml (0.5 mmol) chlorothio-formicacid-O-(4-chlorophenyl)-ester at 15° C. The mixture was stirred for 15 min, concentrated and purified by column chromatography on silica gel with a gradient of CH2Cl2/MeOH 99:1 to 97:3 to yield 92 mg 5-[5-(Allyl-methyl-amino)-pentyl]-2,3-dihydro-indole-1-carbothioic acid O-(4-chloro-phenyl)ester as colorless oil. The corresponding acetic acid salt was prepared by treatment with acetic acid in CH2Cl2 to yield 101 mg 5-[5-(Allyl-methyl-amino)-pentyl]-2,3-dihydro-indole-1-carbothioic acid O-(4-chloro-phenyl)ester-acetic acid as light brown viscous oil, MS: 429 (MH+, 1Cl).
