Reaktionsschritte
To a stirred solution of 4-chloro-7H-pyrrolo[2,3-d]pyrimidine (250 mg/1.63 mmol) in 12 mL of DMF was added 676 mg (4.89 mmol) of potassium carbonate and the resulting mixture stirred at room temperature for 20 min. Benzylchloride (310 mg/2.45 mmol) was added and the new mixture stirred at room temperature for 24 h then filtered, concentrated and the residue purified by silica gel chromatography (3:1 hexanes/ethyl acetate) affording 318 mg (80%) of the title compound. LRMS: 244.1 (M+1).
