Definitions

  • the present invention relates to a improved process for the preparation of 2R, 3S-2-(2,4- Difluorophenyl)-3-(5- fluoropyrimidin-4-yl)-l -(1H-I, 2,4- triazol-1-yl) butan-2-ol It may represented as Formula ( I )
  • Voriconazole exhibits excellent antifungal activity against a wide range of yeasts and filamentous fungi as demonstrated by in vitro and in vivo infection models.
  • Viroconazole has excellent activity in vitro against Aspergillus species, shows efficacy in vivo models of aspergillosis and has demonstrated efficacy in both acute and chronic aspergillosis, with few observed side effects.
  • this drug promises to become an important new agent in the treatment of invasive infections due to Aspergillus and other life- threatening fungal infections.
  • US 5,567,817 patent discloses relates to 2-aryl 3-(3-halo ⁇ yridin-4-yl or 5- halopyridin-4-yl)-l-(lH-l,2,4 triazol-l-yl)alkane-2ol derivatives which are useful in the treatment of fungal infections in animals,including human beings.
  • the US 5567817 discloses process for the preparation comprises of reacting 4- chloro-6-ethyl-5-fluoropyrimidine with l-(2,4-difluorophenyl)-2-(lH- 1 ,2,4- triazol-l-yl)ethanone in presence of Lithium diisopropy amine in Tetrahydrofuron as a solvent to get 2-(2,4-difluoro ⁇ henyl)-3-(4-chloro-5-fluoropyrimidin-4-yl)-l- (lH-l,2,4triazol-l-yl)butan-2-ol the compound, which is further dehaloginated with 5% palladium charcol to give a Racemic Voriconazole and then resolution with camphorsufonic acid in presence of methanol medium and subsequently converted to free base with alkaline medium to give (-) Isomer of Voriconazole of Formula ( I )
  • Voriconazole compound of formula ( I ) which is useful in the treat ment of antistal hence it is important to have alternate process which is cost effective and commercially viable for preparing the compound of Formula ( I ). Therefore the main objective of the present invention is to prepare Voriconzole in improved method, which is cost effective, commercially viable and easily scalable.
  • the Voriconazole is prepared in the present invention, in an improved process that is cost effective and the Voriconazole obtained in this process is suitable for pharmaceutical formulations
  • the present invention provides an improved process for the preparation of Voriconazole and its pharmaceutically acceptable salts
  • the improved process of the present invention comprises, the condensation of 4-chloro-6-ethyl-5- ffluoropyrimidine with 1 -(2,4-difluorophenyl)-2-( IH- 1 ,2,4-triazol- 1 -yl)ethanone in presence of Lithium diisopropylamine as a base and n-Heptane as a solvent mixture with tetrahydrofuron to get the resulting compound 2-(2,4- difluorophenyl)-3 -(4-chloro-5-fluoropyrimidin-4-y I)- 1 -( 1 H- 1 ,2,4triazol- 1 - yl)butan-2-ol as solid.
  • the present invention relates to an improved process for the preparation of 2R, 3S-2-(2,4- difluorophenyl)-3-(5-fluoropyrimidin-4-yl)-l -(1H-I, 2,4- triazol-1-yl) butan-2-ol (commonly known as Voriconazole)
  • the process of the present invention is schematically represented as follows.
  • Voriconazole obtained in the present improved process is free flowing and non- solvated solid; hence it is well suited for pharmaceutical formulations,
  • the process of the present invention is cost effective and getting a more yields, eco- friendly and well suited for scale up.
