Abstract

Abstract The (+), (-) and (+/-) forms of the compounds of the general formula (I) <IMAGE> (I) characterized in that R1 is a halo group; or a lower alkyl, lower alkoxy or lower alkylthio group, each of which may be substituted with one or more halo groups; R2 is hydrogen or a methyl group; or R1 and R2 together form a methylenedioxy, or a difluoromethylenedioxy group or, with the carbon atoms to which they are attached, an aromatic or heteroaromatic ring; and A is one of the groups X or Y <IMAGE> wherein X1 and X2 are the same or different and each is hydrogen or a fluoro, chloro, bromo or methyl group, with the proviso that if X1 is a fluoro group, then X2 should not be a bromo group; and X3 and X4 are the same or different and each is hydrogen or a fluoro group; and Y1, Y2, Y3, Y4, Y5 and Y6 are the same or different groups and each is hydrogen or a fluoro, bromo, chloro, or methyl group.
