Participants

Reaction Steps

To a solution of 2,6-dichloro-9H-purine (1.2 g, 6.35 mmol) in N,N-dimethylformamide (5 mL) was added morpholine (553 mg, 6.35 mmol) followed by diisopropylethyl amine (1.2 mL, 6.87 mmol), dropwise via a syringe. The solution was stirred at room temperature for 1 hour until precipitate formed. The reaction mixture was then poured into water and the precipitate was filtered. Upon drying under high vacuum, 2-chloro-6-morpholin-4-yl-9H-purine was isolated as an off-white solid.
