Reaction Steps

To a solution of purine (360 mg, 3.00 mmol) and 1-bromo-3-chloropropane (1.42 g, 9.0 mmol) in DMF (10 mL) was added K2CO3 (622 mg, 4.5 mmol) at 20° C. The reaction mixture was stirred for 24 h at 20° C. and filtered. The filtrate was concentrated in vacuo and the residue was chromatographed to give 9-(3-chloropropyl)purine (400 mg, 68%) and 7-(3-chloropropyl)purine (136 mg, 23%) as colorless oils.
