Procedure

A mixture of 25 g (0.23 mol) of 3,4-diaminopyridine in 750 mL of ethanol containing 50 mL (63.2 g, 0.83 mol) of carbon disulfide was heated under reflux for 5 hours. The reaction mixture was allowed to cool to room temperature and the beige precipitate which had formed was collected by filtration and allowed to air dry overnight. The product amounted to 33.5 g, m.p. >320° C.
