      Preview
      Description

      The present technology provides a process for the preparation of methanone, the said process comprising steps of:
      (a) condensing a halo-quinoline with an α.-picolyl derivative in the presence of an organic solvent, a base and a phase transfer catalyst at -10 degree to +90 degree C.;
      (b) adding an oxidizing agent to the reaction mixture of step (a) containing the acetonitrile derivative at -10 degree to +90 degree C.;
      (c) cooling the reaction mixture of step (b) and neutralizing with any suitable acid followed by extraction with an organic solvent.
      (d) removing the organic solvent of step (c) and crystallizing the Methanone
      The entire process described above is carried out in the same vessel, without the need to isolate the acetonitrile intermediate. The process is thus an improvement over all existing and known methods.

    • A novel process for -amino acid amides synthesisA novel process for -amino acid amides synthesis
        Preview
        Description

        The present technology provides with an amidation reaction of unprotected a-amino acids in water under neutral conditions with various aliphatic, aromatic and heteroaromatic amines in the presence of coupling reagent l,l'-carbonyldiimidazole (CDI) at ambient temperature to obtain the corresponding a-amino acid amides. This method offers a novel way for amidation of unprotected α-amino acids in one pot reaction. The said amidation reaction can be performed on free as well as hydrochloride salts of amino acids and the side-chain functionality was found to be relatively unaffected by the reagent and reaction conditions. Moreover, the reaction was found to be stereo-conservative in nature, and no apparent racemization of the final products was observed.

            Description

            This technology is related to process of preparing of Erlotinib

            What is Novelty?
            The earlier technologies for preparing [6,7-bis-(2methoxyethoxy)-quinazolin-4-yl]-(3-ethynylphenyl)amine hydrochloride (Erlotinib) having low yield about 50% -75% whereas present technology gives high yield, in addition has significant advantage in terms of time and cost. This technology can produce Erlotinib in less synthetic steps.
