Reaction Steps

Ethyl bromide (0.22 g) was added to a suspension of 3-(R)-(3-fluorobenzyl)pyrrolidine (Intermediate 98, 0.36 g) and potassium carbonate (0.55 g) in acetonitrile and the mixture was stirred at room temperature for 2.5 hours. The mixture was diluted with ethyl acetate, filtered and the filtrate was evaporated to dryness. The residue was triturated with DCM, the solvent was decanted off and evaporated to dryness to give (R)-1-ethyl-3-(3-fluorobenzyl)pyrrolidine (0.24 g) as an oil.
