Reaction Steps

To 25.25 g (0.23 m) of 2,3-diaminopyridine in water is added an aqueous solution of 31.9 g (0.57 m) KOH, followed by 35 g (0.46 m) carbon disulfide. The mixture is heated to reflux for 5 hours, after which the hot mixture is filtered and the filtrate cooled. The cold solution is acidified with acetic acid and the solid is collected, washed with water and air-dried. The crude material is recrystallized in ethanol (3500 ml) with carbon. The recrystallized material weighs 19 g (55% yield).
