  The present invention discloses novel chemical compounds obtained by causing a covalent attachment of a modifying agent of the structure provided for formula 1, to a functional group or a heteroatom of a heterocyclic ring system in chemical compound with improved chemical and biological properties; Wherein : Y is DRUG-CO; DRUG -OCO; DRUG-NRCO, and X is selected from. With a provisio that the modification can be done at more than one functional group in the DRUG. Alternatively : Y is DRUG-CR1 R2, and X is COR, CONRR2, COOR. With a provisio that the N of the drug is attached to CR1 R2. With a provisio that the modification can be done at more than one functional group in the DRUG. G can be selected from iodide, chloride, bromide, mesylate, tosylate or tetra flouroborate or any other pharmaceutically acceptable anion. G can be either one or more counter ions to balance the charge. R, R1 and R2 are independently H, C1-C8 straight or branched chain alkyl - optionally containing 1 -3 heteroatoms selected from O, N, S, SO, or SO2; 3-7 membered cycloalkyl optionally containing 1 -3 heteroatoms selected from O, N, S, SO, or SO2 and or lower alkyl, straight or branched alkyl, alkoxy; alkaryl, aryl, heteroaryl, or alkheteroaryl; or is independently is independently part of 3-7 membered ring optionally containing additional 1 -2 heteroatoms selected from, O, N, S, SO, SO2 and also be optionally substituted with alkoxy, F or CI. The present invention also discloses a method for obtaining these compounds.

  Reaction of 2-iodo-4-methoxybenzoic acid with 3-methoxythiophenol resulted in the acid II which was transformed via the alcohol III and the nitrile IV to [4-methoxy-2-(3-methoxyphenylthio)phenyl]acetic acid (V). Reaction of (2-iodophenyl)acetic acid with 3,4-dimethoxythiophenol gave the isomeric [2-(3,4-dimethoxyphenylthio)phenyl]acetic acid (XI). Acids V and XI afforded by cyclization the ketones VIa and VIb which were converted by reactions with 1-methylpiperazine and titanium tetrachloride to the enamines IXa and IXb. Reduction of these enamines with diborane led to the title compounds. Attempts to reduce the enamines with zinc in acetic acid resulted in hydrogenolysis, the main products being 2,3-dimethoxy- and 3,7-dimethoxy-10,11-dihydrodibenzo[b,f]thiepin (Xab).
