Reaction Steps

2,3-dichloropyrazine (10 g, 67.1 mmol), propan-2-amine (11.90 g, 201 mmol), and 50 mL of THF were mixed in a three-neck flask and stirred at room temperature overnight. The reaction was brought to reflux overnight. The reaction was cooled and the solvent was evaporated. The residue was dissolved in dichloromethane and the salt was filtered. The solvent was then evaporated and the residue was purified by column using dichloromethane as solvent to give 3-chloro-N-isopropylpyrazin-2-amine (6.2 g, 53.8%).
