Reaction Steps
22.4 g (0.12 mol) of 8-amino-7-ethylaminoquinoline and 9 g (0.15 mol) of urea are heated at 160° C. for 2 h, stirring vigorously. The mixture is allowed to cool to 140° C., and 50 ml of water are slowly added dropwise. After further cooling to 100° C., another 100 ml of water are added. The precipitate is filtered off with suction, washed again with hot water and dried under reduced pressure.
