Procedure

220 mg (0.8 mmol) [4-(2,3-Dihydro-1H-indol-5-yloxy)-butyl]-(2-methoxy-ethyl)-methyl-amine in 0.5 ml dioxane were treated with 186 mg (0.9 mmol) chloro-thioformic acid (4-chloro-phenyl)ester in 0.5 ml dioxane at 0° C. The solution was stirred at RT for 3 h, was diluted with water and ether and a saturated aqueous solution of NaHCO3 was added. The inorganic layer was extracted with ether, washed with water and dried over Na2SO4. Column chromatography with CH2Cl2/MeOH 19:1 yielded 230 mg (64%) 5-{4-[(2-Methoxy-ethyl)-methyl-amino]-butoxy}-2,3-dihydro-indole-1-carbothioic acid O-(4-chloro-phenyl)ester as yellow viscous oil, MS: 449 (MH+, 1Cl).
