Versuchsvorschrift

To {2-[2-(6-Chloro-hexyloxy)-ethoxy]-ethyl}-carbamic acid anthracen-9-ylmethyl ester (0.56 g, 1.2 mmol) dissolved in 4 ml dichloromethane was added 2 drops of anisole. The reaction mixture is cooled by means of an ice/NaCl bath. After 10 minutes trifluoroacetic acid (2 ml) is added. The reaction mixture turns dark brown upon addition and is allowed to stir for 30 minutes. All volatiles are removed under reduced atmosphere. The residue is re-dissolved in CH2Cl2 and washed twice with water. The aqueous fractions are frozen and lyophilized overnight. An oily residue remains and is dissolved in anhydrous DMF to be used as a stock solution in further reactions. Mass spectrum, m/e Calcd for C10H23ClNO2+: 224.14 (100%), 226.14 (32%). Found: 224.2, 226.2.
