Abstract
Phenothiazine derivatives are described of the formula ##SPC1## In which X.sub.1 and X.sub.2, which may be the same or different, are H, R, F, Cl, Br, OR, CN, --COR, CH.sub.3, --S--R, --SOR, --SO.sub.2 R or --SO.sub.2 N(CH.sub.3).sub.2, where R is an alkyl group having from 1 to 4 carbon atoms, and the quinuclidine ring is substituted by the group --(CH.sub.2).sub.x -- in the 2- or 3- position, x being 1 or 2 when said group is substituted in the 2-position and being 0 or 1 when said group is substituted in the 3-position (because of electronic hindrance), and their acid addition and quaternary ammonium salts, have valuable pharmacological properties. In particular, these compounds have anti-histaminic, anti-cholinergic, adrenolytic, neuro-sedative, tranquillizing and/or spasmolytic properties. These compounds are prepared by condensing an appropriate phenothiazine with a quinuclidine derivative of the formula ##SPC2## In which x has the above-stated meaning and Z is a halogen atom or a reactive ester group.
