Reaction Steps

4-(3-(2-aminoethyl)-1H-indol-2-yl)-1-butyl-N,N-dimethyl-4-(3-methyl-1H-indol-2-yl)cyclohexylamine (120 mg, 0.255 mmol, mixture of the two possible diastereoisomers in a ratio of approx. 30:70) mixed in dichloromethane (5 ml) with triethylamine (0.12 ml, 0.863 mmol) and cyclopentane sulphonyl chloride (65 mg, 0.385 mmol). After a reaction time of 24 h at 25° C. the reaction mixture was mixed with 1N sodium hydroxide solution (10 ml) and extracted with dichloromethane (3×15 ml). The combined organic phases were dried with Na2SO4 and then filtered. The volatile constituents of the filtrate were completely removed in a vacuum. The residue (yellow foam, 173 mg) was purified by column chromatography [silica gel 60 (25 g); ethyl acetate/methanol 4:1 (250 ml), methanol/30% ammonia 9:1 (100 ml)]. The product was obtained as a beige-coloured solid with a yield of 39 mg (25%) (melting point 111-115° C., AS 11227, mixture of the two possible diastereoisomers in a ratio of approx. 30:70).
