    Abstract: PROBLEM TO BE SOLVED: To provide an efletirizine which is a pharmaceutical having excellent antihistaminic properties, namely, a new crystal form of a 2-[2-[4-[bis (4-fluorophenyl) methyl]-1-piperazinyl]ethoxy]acetic acid dihydrochloride, and to provide a method for preparation of the crystal and to a pharmaceutical composition comprising the same.
    SOLUTION: The invention relates to the new pseudopolymorphic forms of 2-[2-[4-[bis(4- fluorophenyl)methyl]-1-piperazinyl]ethoxy]acetic acid dihydrochloride, defined by the X-ray diffraction pattern, namely, anhydrous 2-[2-[4-[bis(4-fluorophenyl)methyl]-l-piperazinyl]ethoxy]acetic acid dihydrochloride and a monohydrate of the crystal, and relates to the method for preparation of the pseudopolymorphic crystal. The invention also relates to the pharmaceutical composition comprising the pseudopolymorphic crystal, slow release excipient and a cyclodextrine.

    Abstract: The present invention relates to novel substituted [2-(1-piperazinyl)-ethoxy]methyl compounds of the general formula I, in which Ri1 represents the -CONHi2, -CN, -COOH, -COOM or -COORi3, group, M denotes an alkali metal and Ri3 represents an alkyl radical having from 1 to 4 carbon atoms; and Ri2 represents a hydrogen atom or a group -COR4 or -R5, where Ri4 is selected from the groups --ORi6 or -Ri7, in which Ri5 represents an alkyl or alkylaryl radical, Ri6 represents a linear or branched alkyl radical having from 1 to 4 carbon atoms, a haloalkyl, alkylaryl, alkylnitroaryl or alkylhaloaryl radical, andRi7 represents a haloalkyl radical. The invention further relates to a process for the preparation of the above-indicated compounds, as well as to their use for the preparation of compounds which are themselves valuable intermediates for the preparation of 2-[2-[4[(4-chlorophenyl)phenylmethyl]-1-piperazinyl]ethoxy]-acetic acid or 2-[2-[4-[bis(4-fluorophenyl)methyl]-1-piperazinyl]ethoxy]-acetic acid and/or pharmaceutically acceptable salts thereof.
