Reaction Steps

10 g (178 mmol) of potassium hydroxide was dissolved in 400 ml of ethanol, and 20 g (119 mmol) of protocatechuhydrazide was added thereto under stirring at a temperature of at most 5° C. To this solution, 28.0 ml of carbon disulfide was dropwise added over a period of 10 minutes at a temperature of at most 10° C., and the mixture was stirred at a temperature of from 0° to 10° C. for 30 minutes. Then, the precipitates were collected by filtration, washed with ethanol and dried to obtain 25.3 g (yield: 75.3%) of potassium 3-protocatechuoyldithiocarbazate.
