3-Fluor-4,6-dichlortoluol mit reduzierter Bildung von 3-Fluor-2,6-dichlortoluol wird hergestellt, indem man 3-Fluortoluol in Gegenwart von einem Katalysatorsystem zu einem 3-Fluor-6-chlortoluol und 3-Fluor-4-chlortoluol enthaltenden Gemisch chloriert und dieses in Gegenwart eines anderen Katalysatorsystems zu 3-Fluor-4,6-dichlortoluol chloriert.

The synthesis of three series of 1- and 2-substituted imidazo[2,1-d][1,5]benzothiazepines is accomplished starting from 1,5-benzothiazepin-4-ones. All the synthesized compounds were evaluated for their affinity for the benzodiazepine receptor, testing their ability to displace [H-3]Flunitrazepam from bovine brain membrane protein. A few of the tested compounds showed good affinity, in particular compound 9a (K-i = 43.00 nM). The GABA-ratio of the active compounds suggests an antagonist or partial agonist activity. The data obtained allow us to draw some comments on the structure-activity relationships.
