Reaction Steps

A solution of 1.3 ml (25 mmol) of bromine in 10 ml of dichloroethane is added dropwise to a suspension of 5.53 g (25 mmol) of p-nitrophenylcyanothioacetamide and 4.2 g (50 mmol) of sodium hydrogencarbonate in 40 ml of 1,2-dichloroethane. The temperature is maintained at 20° C. by cooling with ice-water. This is followed by 30 minutes of stirring, filtering off with suction and washing with water. Drying in vacuo at 50° C. leaves 4.9 g of a brown powder=89% of theory.
