Reaction Steps

A mixture of 4.2 g (10.9 mmol) [(3S,4R)-1-Benzyl-4-(4-chloro-phenyl)-pyrrolidin-3-yl]-carbamic acid tert-butyl ester, 521 mg (13 mmol) NaH (60%) and 2.54 g (16.3 mmol) iodoethane in 40 mL DMF was stirred for 1 h at 60° C. and evaporated to dryness. The residue was taken up in ethyl acetate and water and extracted further with ethyl acetate. The combined organic layers were washed with brine, dried with Na2SO4, filtered and evaporated to dryness. The residue was purified by column chromatography on silica eluting with a gradient formed from ethyl acetate and heptane to yield after evaporation of the product containing fractions 2.5 g (55%) of the title compound as light yellow viscous oil. MS m/e: 415.3 [M+H]+.
