Definitions

  • the invention relates to an improved process for the production of elvitegravir
  • the carbonate reacts, in the presence of an organopalladium catalyst, with 3-chloro-2- fluorobenzyl zinc bromide (11) (prepared from 3-chloro-2-fluorobenzyl bromide (10) in the conditions of Negishi coupling) producing the protected benzyl quinolone derivative 12a.
  • 3-chloro-2- fluorobenzyl zinc bromide (11) prepared from 3-chloro-2-fluorobenzyl bromide (10) in the conditions of Negishi coupling
  • This is, in the next step, subjected to alkaline deprotection to the intermediate 13, which is, in the final step, subjected to reaction with sodium methoxide providing the end product elvitegravir (Scheme 1).
  • Patent application WO 2011/004389 of Matrix Laboratories describes a synthetic procedure analogous to the method of the basic patent, using protection of the hydroxyl with the tetrahydropyranyl group (Scheme 3).
  • the hydroxyl group of the enamine 22 is, in the next step, protected by a reaction with tert-butyldimethylsilyl chloride and the resulting 23 is subsequently cycled to the protected quinolone derivative 24.
  • both hydrolysis of the ethyl ester and removal of the protecting TBDMS group are performed (Scheme 4).
  • This invention provides an improved process for the production of elvitegravir of formula I,
  • a suitable catalyst e.g. a palladium catalyst.
  • the purity of the intermediate Ila according to HPLC generally exceeds 99%.
  • the general protecting group PG may be, e.g., the trimethylsilyl group or other protecting groups suitable for protection of an oxygen atom, e.g., di-t-butyldimethylsilyl, benzyl, tetrahydropyranyl, tetrahydrofuranyl, others being mentioned, e.g,. in Protective Groups in Organic Synthesis, Third Edition. Theodora W. Greene, Peter G.M. Wuts, John Wiley, 1999. The compounds V and VII conveniently need not be isolated.
  • elvitegravir is obtained by easy removal of the protecting groups - the protecting group on the carbonyl function is removed with water, alcohol; the protecting group on the hydroxyl is removed by reaction with a diluted aqueous acid or water at an elevated temperature. Alternatively, the deprotection can be carried out at the room temperature.
  • PdCl 2 (PPh 3 ) 2 39 mg was added as a catalyst and 10 ml of a solution of 3-chloro-2- fluorobenzyl zinc bromide in tetrahydrofuran (0.5 M) was added at 60°C during 1 h; the mixture was further heated up at 60°C for 1.5 h.
