Procedure
A solution of N,N,N′-trimethylethylenediamine (899 mg, Tokyo Kasei Kogyo) in acetonitrile (31 ml) was cooled to 0° C., added with potassium carbonate (2.21 g, and then slowly added dropwise with tert-butyl bromoacetate (1.56 g, Wako Pure Chemical Industries), and the mixture was stirred at the same temperature for 12 hours. The reaction mixture was added with ethyl acetate, and the insoluble solids were removed by filtration through Celite. The solvent was evaporated under reduced pressure, and the residue was purified by silica gel chromatography (methanol:chloroform=1:10) to obtain the title compound (1.25 g).
