Versuchsvorschrift
In a manner similar to that of Example 2, 3.98 g. of 7H-pyrrolo[3,2-f]quinazoline-1,3-diamine in ca. 260 ml. dry dimethylformamide are reacted with 1.06 g. ca. 50% sodium hydride-mineral oil dispersion and then with 3.63 g. tetrahydrofurfuryl bromide. After stirring the mixture at ca. 25° for 24 hours, 0.21 g. ca. 50% sodium hydride-mineral oil dispersion are added. Stirring is continued for one-hour, 0.73 g. tetrahydrofurfuryl bromide is added, and, after stirring for 6 hours, the reaction mixture is kept at ca. 25° for ca. 70 hours. Processing of the reaction mixture in the manner described in Example 2 (Method A) yields a brown gum which is dissolved in 40 ml. N hydrochloric acid. Dilution of the aqueous acidic solution with 40 ml. acetone gives crystals that are collected and twice recrystallized from methanol-acetone to yield 1.20 g. title compound as a monohydrochloride salt bearing one-third molecule of water per molecule of diamine salt, m.p. 310°-311° (dec.).
