In a 1 L three-necked flask fitted with a reflux condenser were placed 28.2 g of 2-aminopyridine and 60.8 g of iodoethane, and the mixture was stirred under reflux for 2 hours. The reaction mixture was stirred at room temperature for another hour, and the resulting precipitate was filtered under reduced pressure and washed with ethyl acetate (50 ml×2). The residue was dried at room temperature for 3 hours.
