Versuchsvorschrift
2-(4-(Bis(2-hydroxyethyl)amino)phenyl)-6,7-dimethoxyquinazolin-4(3H)-one was synthesized from 2-amino-4,5-dimethoxy-benzamide and 4-(N,N-bis(2-hydroxyethyl)amino)benzaldehyde, using the method described for 5,7-dimethoxy-2-(pyridin-2-yl)quinazolin-4(3H)-one. 2-(4-(Bis(2-hydroxyethyl)amino)phenyl)-6,7-dimethoxyquinazolin-4(3H)-one (72 mg, 24%) was isolated as a yellow solid. Selected data: MS (m/z): 386.15; MP 268-270° C.
