Definitions

  • the present invention relates to an improved process for the preparation of ⁇ -lactam antibiotic compounds in the presence of urea or derivatives thereof and/or amide or derivatives thereof.
  • United States patent US 4,248,780 describes the preparation of zwitterionic antibiotic ampicillm through acylation of silylated 6-ammopen ⁇ c ⁇ llan ⁇ c acid with a phenylglycylchlo ⁇ de hydrochlo ⁇ de by using urea as a base .
  • United States patent US 4,358,588 describes an improved process for the preparation of D- ⁇ -ammo-p- hydroxyphenyl-acetamide-penicillanic acid and cephalosporamc acid derivatives by reacting an appropriate mixed anhydride of a Dane salt with a protected derivative, for example 6-APA or 7-ACA m the presence of a tertiary am e .
  • This type of acylation is referred to as Dane salt coupling reaction.
  • the ⁇ -lactam antibiotic compounds are isolated from an acidic aqueous solution, obtained by acidic hydrolysis of the reaction mixture after the Dane salt coupling reaction, by adding a base and followed by filtration.
  • a manor drawback of the processes for the preparation of ⁇ -lactam antibiotic compounds is the crystallization of unwanted by-products, among which the hydrochloric acid salts of the ⁇ -lactam antibiotic compounds are the most notorious one. These unwanted crystallization of by-products can occur at any stage of the hydrolysis or crystallization procedure.
  • the formation of acid salts of the ⁇ -lactam antibiotic compounds is strongly dependent upon temperature, pH and time during the acidic hydrolysis of the Dane salt coupling reaction.
  • Lower temperatures, a lower pH and prolonged time during the hydrolysis of the Dane salt coupling reaction result the production of an increased amount of acid salt of the corresponding ⁇ - lactam antibiotic compound.
  • the formation of the corresponding acid salt of the ⁇ -lactam during hydrolysis of the Dane salt coupling reaction is reduced but on the other hand the cleavage of the ⁇ -lactam is enhanced.
  • the presence of seeding crystals corresponding to acid salt of the ⁇ - lactam compound, produced during the hydrolysis of the Dane salt coupling reaction facilitate the formation of the acid salts of the ⁇ -lactam antibiotic compounds.
  • ⁇ -lactam antibiotic compounds free of acid salts of the corresponding ⁇ -lactams can be prepared under addition of urea or derivatives thereof and/or amide or derivatives thereof after the Dane salt coupling reaction at low temperature. Urea or derivatives thereof and/or amide or derivatives thereof can also be added during the purification of crude ⁇ -lactam antibiotic compounds during the crystallization phase.

This method has nowhere been described or suggested for ⁇ -lactam compounds until now.
  • the present invention provides an improved process for the preparation of ⁇ -lactam antibiotic compounds the presence of urea or derivatives thereof and/or amide or derivatives thereof.

  • the acid that is added may assist m the acid hydrolysis of the reaction mixture from the acylation reaction.

  • the acid is hydrochloric acid.
  • the temperature during the crystallization may vary.
  • the crystallization temperature is between -10°C and 50°C, preferably between -5°C and 35°C. It will be clear for the skilled the art that the preferred conditions will depend on the ⁇ -lactam compound to be prepared.
  • the ⁇ -lactam antibiotic compounds can be isolated n a conventional manner, by adjusting the pH to the lsoelect ⁇ c point of the corresponding ⁇ -lactam compounds .
  • the ⁇ -lactam compounds are for instance penicillins and cephalosporms. Examples of penicillins are amoxicillm, ampicillm and epicillm. Examples of cephalosporms are cefaclor, cefadroxil, cefetamet, cefotaxim, cephalex , cephaloglyc , cephradme and cefroxadine. - 6 -
