| titleOfInvention | Process for producing zaltoprofen and its derivatives |
| abstract | The present invention relates to a method for producing zaltoprofen or a maltoprofen derivative by a cyclization reaction in the form of a Friedel-Crafts reaction type, wherein 6.5 times Or less of polyphosphoric acid is used as a condensing agent so that impurities such as a detectable amount of a dimer are not produced at a purity sufficient for use as a pharmaceutically active ingredient, The present invention relates to a process for preparing zaltoprofen or zaltoprofen derivatives on a simple, economical and industrial scale. Specifically, in the presence of at least one organic solvent selected from the group consisting of 1,1,2-trichloroethane, methylcyclohexane, cyclohexane, n-heptane, etc., the raw material for pulmonary exchange is intramolecularly cyclized To a process for producing zaltoprofen or a maltoprofen derivative by ring closure by a reaction. |
