phenolic group. A noveldibenzazecinederivative was prepared, with methylenedioxy moiety, connecting C(2) amd C(3), instead of the 3-OH group. The newly synthesized derivative 3 showed high affinities similar to the lead LE404, displaying nanomolaraffinities for all dopaminereceptor subtypes. Its dibrominated derivative 4, though exhibiting almost a fivefold decrease in affinities, still displayed
