Abstract
This paper describes a simple, cost-effective and one pot process for racemization of undesired (S)-3-(carbamoylmethyl)-5-methylhexanoic acid, which produced during the resolution step. The unwanted S-enantiomer was converted into the symmetrical glutarimide derivative in the presence of a catalytic amount of DMAP or pyridine in refluxing toluene followed by hydrolysis with an alkali.
