Reaction Steps
A mixture of (R)-2-[4-(4-chloro-benzyl)-phenoxymethyl]-pyrrolidine hydrochloride (1.37 g, 4 mmol), methyl 4-bromobutyrate (916 mg, 5 mmol), and potassium carbonate (1.12 g, 8 mmol) in DMF (15 mL) was stirred for 60 h at rt. The solvent was removed in vacuo to obtain the crude mixture. The mixture was diluted with 30 mL of water and extracted with ethylacetate (130 mL). The aqueous layer was re-extracted with ethyl acetate (2×100 mL). The combined organic layers were dried over anhy. Na2SO4 and the solvent was removed in vacuo to obtain the crude mixture, which was purified by silica gel flash chromatography to obtain the title product (570 mg, 35%).
