Versuchsvorschrift
0.35 g (0.87 mmol) trans-N-[4-(3-Cyano-propoxy)-cyclohexyl]-N-methyl-4-trifluoromethyl-benzenesulfonamide in 6 ml ethanol were treated with HCl gas at low temperature for 20 min. The mixture was kept at −20° C. for 48 h, was concentrated under reduced pressure to yield 400 mg (quant.) trans-4-{4-[Methyl-(4-trifluoromethyl-benzenesulfonyl)-amino]-cyclohexyloxy}-butyrimidic acid ethyl ester as light brown oil, MS: 451 (MH+).
