Vorschrift

7.4 ml of 4M NaOH are added to a suspension of 1.69 g of [trans-4-(3-ethoxycarbonyl-thioureido)cyclohexyl]carbamic acid tert-butyl ester in 10 ml of H2O and 15 ml of EtOH. The mixture obtained is kept at 90° for 30 minutes at RT. The precipitate formed is filtered and washed with diethylether. (trans-4-Thioureido-cyclohexyl)-carbamic acid tert-butyl ester is obtained.
