The optical resolution of (Β±)-cizolirtine was accomplished with excellent results (>99% ee) by means of crystallization with (+)-or (-)-di-p-toluoyltartaric acid. The optical purity of the samples was controlled by three independent methods: 1 H NMR, capillary electrophoresis (CE) (using β€-cyclodext
