Abstract
Reactions of 2,4,5-trichlorothiophenol (II) with 2-iodobenzoic acid and 2,3-dichlorothiopheno with 3,5-dichloro-2-iodobenzoic acid gave the acids III and IX which were cyclized to thioxanthones VI and XV. Reactions of these ketones with 3-dimethylaminopropylmagnesium chloride afforded the amino alcohols VII and XVI which were transformed by the acid catalyzed dehydration to the title compounds I and VIII. 2-Chloro-9-[1-(2-hydroxyethyl)-4-piperidylidene]thioxanthene (XVII) was obtained by a modified synthesis. Compound I is inactive in the line of the CNS effects but it has high inhibitory activity in the in vitro tests towards gram-positive microorganisms. Compound XVII has properties of a mild tranquillizer.
