Procedure
The 7-Imino-7H-indolizino[5,6,7-ij]isoquinoline (110 g.) and N sodium hydroxide solution ( ##SPC14## cc.) in ethanol (4.4 liters) and water (4.4 liters) are heated under reflux for 4 hours. After cooling, 7H-indolizino[5,6,7-ij]isoquinolin-7-one (108.1 g.) is obtained in the form of yellow needles melting at 264° C.
