PROCESS FOR PURIFICATION OF CILOSTAZOL

The present invention provides a process for preparing high purity cilostazol. The process comprises: (a) adding crude cilostazol to an acid selected from the group consisting of oxalic acid, maleic acid, sulfuric acid, and a mixture thereof to form a cilostazol salt; and (b) recovering cilostazol through adding a base to the cilostazol salt.
