Procedure

Description 74 was prepared in an analogous manner to that described for Description 73 from 686 mg (mmol) of 3-bromo-5-(2-oxo-pyrrolidin-1-yl)-benzoic acid methyl ester (D9a) and cyclohexene which yielded 207 mg (30%) of 3-cyclohex-2-enyl-5-(2-oxo-pyrrolidin-1-yl)-benzoic acid methyl ester, 3-cyclohex-3-enyl-5-(2-oxo-pyrrolidin-1-yl)-benzoic acid methyl ester and 3-cyclohex-1-enyl-5-(2-oxo-pyrrolidin-1-yl)-benzoic acid methyl ester (D74) after purification by flash chromatography on silica gel (iso-hexane/EtOAc: 5/1)
