Reaktionsschritte

10.0 g (53.6 mmol) of 2-chloro-3'4'-dihydroxyacetophenone was dissolved in 100 ml of methanol, and then 5.90 g (53.6 mmol) of ammonium dithiocarbamate was added thereto. The mixture was stirred at room temperature for 30 minutes. The solvent was distilled off under reduced pressure. To the residue, water was added to adjust the mixture to pH2.0, and then the mixture was extracted twice with ethyl acetate. The extract was dried over anhydrous sodium sulfate and-then concentrated. The crystal residue was washed with diethyl ether to obtain 8.80 g (yield: 72.9%) of the above-identified compound.
