Process for producing optically active flurbiprofen |
摘要 |
The present invention provides a method for producing optically active flurbiprofen. The method of the present invention includes mixing racemic flurbiprofen and (S)- or (R)-3-methyl-2-phenylbutylamine in an organic solvent to produce a diastereomeric salt; and treating the diastereomeric salt with an acid in a second solvent. In the method of the present invention, flurbiprofen having a desired absolute configuration can be obtained very efficiently without repeating the procedure for optical resolution a plurality of times.
