Definitions
- Japanese patent application 2/790 describes a method involving reacting silyated 7-AVCA with acyloxyiminoacetylhalides followed by removal of acyl group from the condensed product to obtain cefdinir.
- the process requires rigorous anhydrous conditions for the condensation step.
- the preparation of starting compound requires several synthetic steps and includes the use of phosphorous pentoxide thus making the process unsuitable for production at an industrial scale.
- WO 01/79211 describes a process for preparing cefdinir, wherein the protecting groups at the carboxyl, hydroxyimino, and amino positions are removed by a mixture of an organic protonic acid and a perhalogenic acid.
- the use of perhalogenic acid at large scale is undesirable.
- R' represents C ⁇ -C alkyl or phenyl or R' together with phosphorus and oxygen atoms to which R' is attached can form a 5 to 6-membered heterocycle, which is reacted with a 3-cephem derivative having the following Formula P(v),
- the compounds of Formula II may be converted to cefdinir by conventional methods for removal of the trityl group i.e. acid hydrolysis.
- an important characteristic of the compound of the present invention is that the removal of the trityl group requires very mild conditions.
- the p-toluene sulfonic acid addition salt provided by U.S. Patent No. 6,093,814 does not undergo complete hydrolysis without addition of an acid.
- the conversion of compounds of Formula II to cefdinir may be easily achieved either without use of any acid under reflux temperature, or with an acid at ambient temperature.
- Figure 2 shows the x-ray powder diffraction pattern of a sample prepared according to Example 2.
- the dichloromethane layer was then separated and the aqueous layer was washed with dichloromethane (300ml).
- the pH was adjusted to 5.0 with hydrochloric acid and treated with activated carbon.
- the aqueous layer was acidified to pH 2.5-3.0 with 4N hydrochloric acid.
- the resulting precipitate was collected by filtration and dried to afford 29.0g of cefdinir (yield: 73%).
