4-Fluorobenzyl chloride → 6-Amino-2-chloro-9-(4-fluorobenzyl)purine

참여 물질

반응 단계

6-Amino-2-chloropurine (5.02 g) and potassium carbonate (5 g, 36 mmol) were suspended in DMF (200 ml) and thereto was added 4-fluorobenzyl chloride (5 ml, 42 mmol). The mixture was stirred at room temperature for 3 hours. The reaction mixture was concentrated in vacuo to dryness, and to the residue was added water. The mixture was extracted with chloroform and the organic layer was washed with water, dried on sodium sulfate and concentrated in vacuo to dryness. The residue was purified with silica gel chromatography (2% methanol/chloroform) to give the subject compound (162 g).
