The process development and improvements for route selection, adapted to large scale for the pilot-scale preparation of SL65.0102-10, an N-diazabicyclo[2.2.2]-octylmethyl benzamide, a 5-HT3 and 5-HT4 receptor active ligand for the treatment of neurological disorders such as cognition impairment, are described in this article. Notable steps and enhancements are compared to the original route, including the improvement of a chiral epoxide synthesis by shortening the number of chemical steps, the deprotection of a quaternary ammonium salt, and the redesign of the final amidification coupling to avoid chromatography.
