New imidazoquinazoline compounds having the general formula
wherein A together with theα-marked carbon atom and the β-marked nitrogen atom is one of the groups
wherein R⁴, R⁵, R⁶ and R⁷ independently are hydrogen, halogen C₁₋₆-alkyl, aryl or aralkyl R¹ is
cyano or CO₂R⁸,
wherein R⁸ is hydrogen, C₁₋₆-alkyl or C₃₋₇-cycloalkyl, trifluoromethyl or C₁₋₆-alkoxymethyl,
R² and R³ independently are hydrogen, halogen, CN, C₁₋₆-alkyl, C₂₋₆-alkenyl, C₂₋₆-alkynyl, trifluoromethyl, C₁₋₆-alkoxy, dialkylaminoalkoxy, aralkoxy, aryloxy which may be substituted with halogen or alkoxy, a cyclic amino group, or NR⁹R¹⁰ wherein R⁹ and R¹⁰ independently are hydrogen or C₁₋₆-alkyl.
