Participants

Reaction Steps

1.17 g (9.2 mmol) of 1,3-dichloroacetone is added dropwise to a solution of 2 g (9.2 mmol) of 2-amino-5-bromo-3-dimethylaminopyrazine. After 3 hours under reflux, the alcohol is evaporated off under reduced pressure and the residue taken up with water, alkalinized and extracted with dichloromethane.
