Reaction Conditions

Reaction Steps

6-Chloro-3-pyridinecarbonitrile (5.0 g) was dissolved in 1,4-diaminobutane (50 ml), and the solution was stirred at 170° C. for 2 hours with heating. Diethyl ether and distilled water were added to the reaction mixture, the layers were separated, and the aqueous layer was extracted with diethyl ether. The aqueous layer was saturated with sodium chloride, and the resulting mixture was extracted with chloroform. The resulting organic layer was dried over anhydrous magnesium sulfate, and filtered, and the filtrate was concentrated under reduced pressure to obtain the title compound (4.77 g).
