    • Preparation of thiazol-2-yl amino carbonyl indole derivatives, their salts or solvates involves reacting N-(amino-thioxo-methyl)-1H-indole-2-carboxamide with an alpha -halogen-ketone. Preparation of thiazol-2-yl amino carbonyl indole derivative of formula (I), its salts or solvates involves reacting an N-(amino-thioxo-methyl)-1H-indole-2-carboxamide of formula (II) with an alpha -halogen-ketone of formula R8>-C(O)-CH(X)-R9>'> (III). (I) or its solvate is then transformed into its salt or liberated from its salt.

Independent claims are also included for: (1) compounds of formulae (II) and (III); (2) preparation of (II) by transforming 1H-indole-2-carboxylic acid of formula (V) into 1H-indole-2-carboxylic acid halogenide of formula (VI), reacting (VI) with potassium-thiocyanate in the presence of a diprotic-aprotic solvent (preferably acetone or methyl-ethyl-ketone) and reacting the isothiocyanate of formula (VIII) with ammonia or ammonium hydroxide; and (3) preparation of (III) by acylating a methoxy benzene of formula (X) with an acid-chloride of formula Cl-C(O)-CH2-(CH2)o-S-(CH2)p-R1>4> (XI) in the presence of a Lewis acid (preferably titanium-tetrachloride or aluminum chloride), and halogenating R8>-C(O)-CH2-R'9> (IX).
