Procedure

To 4-methoxy-7H-pyrrolo[2,3-d]pyrimidine (3, 3.20 g, 21.4 mmol) in 280 mL of dichloromethane, N-iodosuccinimide (5.3 g, 24.0 mmol) suspended in dichloromethane was added. The reaction was stirred at room temperature for 2 hours, then poured into water and extracted with ethyl acetate. The organic layer was dried over sodium sulfate, filtered and the filtrate concentrated under vacuum. The resulting material was washed with ethyl acetate and hexane to provide the desired compound (35, 4.80 g).
