Reaction Steps
A mixture of 1 g of 6-(2-chloroethyl)-5,11-dioxo-5,6-dihydro-11H-indeno[1,2-c]isoquinoline (IV, X=2, m.p. 214°-215° C.), 1 g of dry 2-aminoethanol and 1 g of anhydrous potassium carbonate in 30 ml of anhydrous dimethylformamide is treated by warming to 100°14 110° C. and kept at this temperature for two hours. The hot mixture is filtered and the product collected on filter washed with 10 ml of ethanol. After twelve hours of standing in refrigerator (5° C. the eliminated crystallic substance is separated by suction, washed with ethanol and dried at temperature of 60° C. The yield 0.7 g (65% of theory), m. p. of the product is 184° C. It is possible to purify the substance as in Example 1.
