Reaction Steps

Ethane-1,2-diamine (200 mg) was added to a solution of 5-bromo-2-chloro-pyrimidine (500 mg) and triethylamine (1 mL) in ethanol (10 mL) at 0° C. The reaction mixture was stirred under nitrogen at room temperature overnight. The formed mixture was concentrated to give crude N1-(5-bromopyrimidin-2-yl)ethane-1,2-diamine. Yield: 687 mg (100% of theory).
