실험 절차

4-Cyclopentyl-7H-pyrrolo[2,3-d]pyrimidine (48, 0.099 g, 0.53 mmol) was dissolved in 3.4 mL of dichloromethane under an atmosphere of nitrogen and N-iodosuccinimide (0.131 g, 0.582 mmol) was added. The mixture was stirred overnight, then quenched with aqueous sodium thiosulfate. The aqueous layer was separated and washed with ethyl acetate. The organic layers were combined and washed with water, brine, dried over sodium sulfate and filtered. The filtrate was concentrated under vacuum to provide the desired compound (49, 0.616 g), used in the next step without further purification. MS (ESI) [M+H+]+=313.9.
