Komponenten

Versuchsvorschrift

To 180.0 g (1.63 mols) of ammonium dithiocarbamate was added 1.5 liters of isopropyl alcohol, the mixture was stirred and then 268.9 g (1.63 mols) of ethyl 4-chloro-3-oxobutanoate was added dropwise to the mixture. After stirring the resultant mixture for 3 hours under refluxing, 300 ml of water was added to the reaction mixture, the mixture was cooled to room temperature and crystals formed were collected by filtration under a reduced pressure to obtain crude crystals. The crude crystals were recrystallized from ethyl acetate to obtain 188 g (yield 57%) of 4-ethoxycarbonylmethyl-2-mercaptothiazole.
