Abstract

Abstract The 3H-imidazo [4, 5-c] pyridazine, 1H-imidazo [4, 5-d] pyridazine, and 1H- benzimidazole analogues of the potent anticonvulsant purine 9-(2-fluorobenzyl)-6- methylamino-9H-purine (1, 78U79) were synthesized and tested for anticonvulsant activity. The 3H-imidazo [4, 5-c] pyridazines 8 and 9 were prepared in five stages from 3, 4, 5- trichloropyridazine (2). The 1H-imidazolo [4, 5-d] pyridazine 15 was synthesized in four ...
