title: Enantiomer resolution of nefopam hydrochloride, a novel analgesic: a study by liquid chromatography and circular dichroism spectroscopy.
abstract: Nefopam, a potent analgesic, has been completely resolved into enantiomers on a preparative scale by low-pressure liquid chromatography on swollen, microcrystalline triacetylcellulose. The enantiomerically pure hydrochlorides were prepared from the base, and the circular dichroism spectra of the free base and the hydrochloride are reported.
