実験手順

14.0 g (97 mmol) of the compound of Example I and 27.95 g (97 mmol) of 4-chloro-N-(4-oxo-cyclohexyl)benzenesulphonamide are refluxed for 5 hours in 190 ml of ethanol and 36 ml of concentrated sulphuric acid, then the mixture is cooled and diluted with 300 ml of water. The mixture is extracted 4 times using 250 ml of ethyl acetate each time, and the organic phase is dried using sodium sulphate, filtered with suction over kieselguhr and evaporated. The residue is stirred with methylene chloride and dried in a high vacuum.
