반응 단계
Clopidogrel base was dissolved in acetone to obtain a clear solution. To it was added p-toluene sulfonic acid at room temperature. The reaction mixture was heated to reflux temperature for 2 to 10 hrs. The solvent was evaporated to dryness under reduced pressure to obtain amorphous Clopidogrel tosylate.
