Substituted (10H-phenothiazin-10-yl)propyl-1-piperazines of the formula STR1 wherein R1, R2, R3, A, X, m, n and s are as hereinafter set forth, are described. The compounds of formula I, which contain a piperazine moiety combined by an ether linkage to different phenolic moieties, are useful as orally active long lasting antipsychotic agents.
Process for inverting the configuration in optically active compounds

, (2008/06/13)
The invention relates to a process for inverting the configuration in optically active compounds of the formula STR1 in which Ar1 represents a monocyclic or polycyclic, carbocyclic or heterocyclic radical that has at least one ring of aromatic character and is bonded to the oxygen atom by way of a ring carbon atom, preferably of the ring of aromatic character, and R1 represents an optionally substituted aliphatic, cycloaliphatic or araliphatic hydrocarbon radical, or the salts thereof, characterised in that an optically active compound of the formula STR2 having a R(+) or S(-) configuration, in which R2 represents a monocyclic or polycyclic, carbocyclic or heterocyclic radical, or an optionally substituted aliphatic, cycloaliphatic or araliphatic hydrocarbon radical, is converted, by treating with a strong oxygen-containing inorganic or organic acid or halides thererof, into an optically active compound of the formula STR3 in which X? represents the anion of a strong, oxygen-containing inorganic or organic acid or of a halogen atom and the resulting compound of the formula III is hydrolysed, optionally by way of the corresponding free base as intermediate, to form a compound of the formula I of a configuration opposite to that of the starting material used and, if desired, a free compound of the formula I is converted into a salt or a resulting salt is converted into the free compound.
