Process for preparing the S enantiomer of a benzamide

摘要

Process for preparing the S enantiomer of a benzamide characterised by the condensation reaction of S-3- aminoquinuclidine monohydrochloride with 2-cyclopentoxy-4- amino-5-chlorobenzoic acid in the presence of a dehydrating agent, and once the reaction is complete isolating the compound by normal methods.
