Reaction Steps
Ethylenediamine (30 g) was dissolved in acetonitrile (200 ml), and pyrazinylmethyl chloride (12.9 g) was added dropwise to this solution at 5° to 10° C. After addition, the mixture was stirred at room temperature for 1 hour. Then, a 50% aqueous solution of sodium hydroxide (8 g) was added, and thereafter, volatile materials were removed at a bath temperature of 60° C. under 5 mmHg. The inorganic salt was then removed by filtration. Thus, N-(pyrazinylmethyl)ethylenediamine (14.1 g) was obtained as a colorless oil.
