反応手順
5.5 g (39.7 mmol) of 6-chloronicotinonitrile were dissolved in 70 ml of DMSO, and 10.2 g (63.5 mmol) of N-Boc-ethylenediamine and 11 g (79.4 mmol) of potassium carbonate were added. The mixture was stirred at 90° C. for 12 h. The residue was taken up in a mixture of water and ethyl acetate. The organic phase was washed with saturated aqueous sodium chloride solution, dried over magnesium sulfate and concentrated on a rotary evaporator. The residue was chromatographed on silica gel 60 (mobile phase: cyclohexane/ethyl acetate 10:1 to 2:1). This gave 7.9 g (77% of theory) of the product as a solid.
