The enantiomeric excess (ee) was measured by HPLC analysis carried using a Waters 510 HPLC system. Chiracel OD packed in a ss column of 4.6 mm i.d. X 250 m was used. Isocratic elution was applied with a mobile phase consisting of n-Hexane 90% and isopropanol 10% at a flow rate of 0.8 mL/ min and a pressure of 125 psi. UV detection at 243 nm was used. Retention time 5.5 and 7.8 min.
