10 g (58.74 mmol) of [bis(methylthio)methylene]malononitrile and 6.5 g (64.61 mmol) of cyanothioacetamide are initially charged in 20 ml of DMF, and 16.4 ml (117.5 mmol) of triethylamine are added dropwise at room temperature. The mixture is stirred at room temperature for 8 h and allowed to stand for a further two days. The mixture is then added to 250 ml of 3 N hydrochloric acid. The resulting precipitate is filtered off with suction, washed with water and acetone and dried. This gives a yellow powder.
