Process for preparing azetidinone derivatives |
| abstract |
A process for preparing an azetidinone derivative represented by the formula (1)wherein R<sup>1</sup> represents a substituted or unsubstituted aryl group, a substituted or unsubstituted phenylmethyl group or a substituted or unsubstituted phenoxymethyl group, R<sup>2</sup> represents a hydrogen atom or a group for protecting carboxylic acid and Ar represents a substituted or unsubstituted phenyl group, the process comprising reacting a thiazolineazetidinone derivative represented by the formula (2)wherein R<sup>1</sup> and R<sup>2</sup> are as defined above with a sulfonyl bromide represented by the formula (3)wherein Ar is as defined above in water-containing organic solvent. |
