Versuchsvorschrift

In a manner similar to that of Example 2, 7.97 g. 7-H-pyrrolo[3,2-f]quinazoline-1,3-diamine in 350 ml. dry dimethylformamide is converted to the Nind-sodium salt with 2.31 g. ca. 50% sodium hydride-mineral oil dispersion and the salt is treated with 4-acetylbenzyl bromide (10.23 g.) in 10 ml. dry dimethylformamide. After stirring for 3 hours, the reaction mixture is treated with 5 ml. gl. acetic acid and freed of solvent. The residue is stirred with excess aqueous potassium carbonate solution, washed with water, with ether, and dried. Two recrystallizations of the crude product from methanol and thorough drying provide 9.82 g. of title compound, m.p. 224°-225°.
