The single crystal XRD also confirms the structure of iodo product 13 and indicates the product to be a racemate of RandS isomers (figure 3).
To develop a single stereoisomer from a mixture that has already been studied non-clinically, an abbreviated, appropriate pharmacology/toxicology evaluation could be conducted to allow the existing knowledge of the racemate available to the sponsor to be applied to the pure stereoisomer.
Today it's unlikely that the selection of one enantiomer from a known racemate would result in patent protection as it is well known that different stereoisomers can have much different activity.
