    • PURPOSE: A method for the preparation of macrolide antibiotic agent, clarithromycin, represented by structural formula (1) is provided. Also, provided is a method for preparing clarithromycin from 1,3-benzodithiol-2-sulfonic acid group that forms clarithromycin salt which precipitates into crystals in reaction solution thereof, thereby purification step of clarithromycin is significantly simplified. CONSTITUTION: A novel intermediate, erythromycin A 9-O-benxodithide oxime intermediate is useful for synthesis of clarthromycin prepared by reacting erythromycin A 9-Oxime or hydrochloride thereof with 1,3-benxodithiol-2-ylium tetrafluoroborate (BDTF) represented by formula (III), wherein Y1 and Y2 are hydrogen atoms or trimethylsilyl groups. Purified clarthromycin is prepared in a high yield which has broad antimicrobial activity as a macrolide antibiotic agent by using 1,3-benzodithiol-2-ylium tetrafluoroborate (BDFT), which can easily be synthesized from anthranilic acid and used as a protecting group for oxime.
