title: On-line recovery of trimeprazine enantiomers following chiral separation by reversed-phase high-performance liquid chromatography using a beta-cyclodextrin-containing mobile phase.
abstract: A procedure is described which allows the on-line recovery of enantiomers following semi-preparative chiral separation by RP-HPLC using beta-cyclodextrin in the mobile phase. By this method, the phenothiazine antihistamine trimeprazine (I) was resolved into its antipodes at greater than 95% optical purity at a throughput of more than 1 mg of each enantiomer per hour, using 4 mm i.d. columns. The recovered trimeprazine was found to be free from cyclodextrin.
