Participants

Reaction Steps

3-Aminopyridine (38.96 g, 413.96 mmol) and cyanamide (21.40 g, 509.2 mmol) in 12N hydrochloric acid (271 mL) were stirred at 140-150° C. for 4 hours. Concentration under reduced pressure provided a heavy syrup which was purified by recrystalization from 1:1 isopropanol:diethyl ether (500 mL) to provide 60.2 g of the desired product as a white solid.
