Reaction Steps

A mixture of 1-[2-(4-bromo-phenyl)-2-(3-methoxy-phenyl)-ethyl]-5-ethoxy-pyrrolidin-2-one (472.2 mg, 1.13 mmol) and MSA (2 N in ethanol, 10 mL) was stirred for 2 h at rt. The mixture was diluted with EtOAc, washed with satd. aq. NaHCO3 and brine, dried (MgSO4), and concentrated to give a colorless oil. Chromatographic purification (EtOAc/hexanes) yielded 325.4 mg (78%) of the desired product as a mixture of cis and trans diastereomers. The diastereomers were separated by normal-phase HPLC.
