Reaction Steps

1-(1,3,4,6,7,11b-Hexahydro-2H-benzo[a]quinolizin-2-yl)-3-benzoylurea hydrochloride (0.98 g) was refluxed in 2N sodium hydroxide solution (50 ml) for 4 hours. The solution was filtered and the residue washed with water, then ethanol, and finally ether before drying to give the title compound (0.46 g) melting point 235° C. C14H19N3O requires: C, 68.54%; H, 7.81%; N, 17.13%. Found: C, 68.53%; H, 7.79%; N, 17.33%.
