Reaction Steps

2-Bromopyridine (10.00 g, 63.3 mmol) was added dropwise to 1,2-diaminoethane (76.00 g, 126.6 mmol) under nitrogen at 20° C. with stirring. The reaction mixture was stirred at 20° C. for 4 h. and then under reflux for 24 h. The reaction mixture was concentrated in vacuo and purified by column chromatography on flash silica eluting with dichloromethane, ethanol and ammonia (30:8:1) to afford the title compound as a red oil (1.23 g).
