الإجراء التجريبي

1.9 g of 6-(4-(2-aminoethyl)phenyl)-6-(3-pyridyl)hexanoic acid are suspended in 150 ml of dioxan and 20 ml of 5% potassium carbonate solution are added thereto. 1.54 g of 4-chlorobenzenesulphonic acid chloride in 20 ml of dioxan are added to this mixture at ambient temperature. After 5 hours it is rotary evaporated to dryness, the residue is taken up in a little sodium hydroxide solution and then precipitated with dilute acetic acid. The precipitate is collected, dried and then chromatographed over a silica gel column using chloroform/methanol (10:1) as eluant.
