Isopropylamine → (5-Bromo-2-chloropyrimidin-4-yl)isopropylamine

Participants

Reaction Steps

3.3 ml (23.8 mmol) of triethylamine and 2.0 ml (23.3 mmol) of 2-aminopropane are added to a solution of 4.87 g (21.4 mmol) of 5-bromo-2,4-dichloropyrimidine in 23 ml of acetonitrile at 0° C. The reaction mixture is stirred at room temperature overnight and then the solvent is stripped off. The resulting residue is purified by chromatography (dichloromethane/ethanol 8:2). 4.09 g (16.4 mmol; yield: 76%) of the product are obtained.
