During reverse phase chromatography, the chiral fragment-B of Boceprevir i.e methyl (1R, 2S, 5S)-6, 6-dimethyl3-azabicyclo[3.1.0]hexane-2-carboxylate hydrochloride was separated along its cis isomer, acid impurity and ester impurity. The R and S isomers of Trans isomers were separated by chiral chromatography; the chiral S isomer was characterized by the 1D NMR, FT-IR, Mass, SOR, X ray studies and differential scanning colorimetry.
