Abstract
A process for preparing ondansetron by transamination of an ondansetron structural analog that can be readily prepared conveniently by a Mannich reaction is provided. The process represents an improvement upon known procedures for making ondansetron by transamination because of its rapid rate, selectivity and the ease with which the product can be isolated from the reaction mixture.
