To a suspension of tert-butyl N-[(1S,2S)-2-aminocyclopentyl]carbamate (CAS number 586961-34-4; 500 mg, 2.50 mmol) and potassium carbonate (518 mg, 3.74 mmol) in DMF (5 ml) was added (bromomethyl)benzene (CAS number 100-39-0; 356 μl, 3.00 mmol). The reaction was stirred at room temperature for 24 hours. To this was then added further (bromomethyl)benzene (CAS number 100-39-0; 356 μl, 3.00 mmol) and stirring was continued for 24 hours. The reaction mixture was diluted with ethyl acetate (40 ml) and washed with water (3×30 ml) and brine (30 ml). The organics were filtered through a hydrophobic frit and concentrated in vacuo. This was then purified by column chromatography (silica, 0-100% ethyl acetate/petrol) to afford the title compound.
