A mixture of 2,3-diaminopyridine (45 g), ethanol (500 ml), triethylamine (42 g) and benzyl bromide (70.5 g) was stirred at room temperature for 3 days. The solvent was evaporated in vacuo and the residue partitioned between chloroform (500 ml) and water (400 ml). The organic layer was eparated, filtered through a silica gel plug and evaporated in vacuo. The residue was triturated with hot chlorobutane to yield a brown powder.
