Reaction Steps

To 4-[2-Amino-1-(2-fluoro-phenyl)-ethyl]-piperazine-1-carboxylic acid tert-butyl ester (207) (0.18 g, 0.56 mmol) in DMF (3 mL) was added 1-bromo-2-ethyl-butane (0.083 mL, 0.59 mmol) and potassium carbonate (0.093 g, 0.68 mmol). The reaction was allowed to stir at room temperature for 18 h. The reaction mixture was then diluted with EtOAc (30 mL) and H2O (30 mL). The organic phase was dried with sodium sulfate and concentrated to dryness. The crude material was purified by chromatography (silica gel 60 mesh, eluting with 3% (2M NH3 in MeOH) in MeCl2) yielding 0.13 g (59%) pure product.
