실험 절차

3.00 g (18.6 mmol) of 2-chloro-5-chloromethyl pyridine was dissolved in 20 ml of anhydrous DMF, 1.75 g (18.6 mmol) of 2-aminopyridine was added thereto, and the resulting mixture was stirred at 80° C. for 8 hours and at room temperature for 5 hours. After the reaction was completed, DMF was distilled off under reduced pressure, acetonitrile was added thereto to precipitate a solid, and the solid was collected, washed well with acetonitrile and then dried to obtain 2.07 g (yield 44%) of 1-[(6-chloropyridin-3-yl)methyl]pyridin-2(1H)-imine hydrochloride.
