Procedure

4 g (0.03 mol) of nitromethane and 6 ml (0.05 mol) of carbon bisulfide were placed in a 100 ml three-necked flask and 10 ml of ethanol was added as a solvent, and then the solution was stirred. To the resulting solution was added slowly and dropwise the solution of 8 g (0.14 mol) of potassium hydroxide in 40 ml of ethanol at room temperature over nearly 30 min. Since the reaction was exothermic, the rate of addition depended on the reaction temperature which was preferably between 30-35° C. After the addition was complete, the mixture was further stirred for 2 hours, filtered to obtain a crude product, which was a brown yellow powder in 72% yield.
