Object of the present invention is an improved process for the preparation of key intermediates for the synthesis of Eltrombopag, passing through/using intermediate 5'-Chloro-2'-hydroxy[1,1'-biphenyl]-3-carboxylic acid alkaline metal salt of formula: wherein A is an alkaline metal.
Invented are non-peptide TPO mimetics. Also invented are novel processes and intermediates used in the preparation of the presently invented compounds. Also invented is a method of treating thrombocytopenia, in a mammal, including a human, in need thereof which comprises administering to such mammal an effective amount of a selected hydroxy-1-azobenzene derivative.
