실험 절차

To 4-cyclopentyl-5-iodo-7H-pyrrolo[2,3-d]pyrimidine (49, 0.161 g, 0.514 mmol) in tetrahydrofuran, sodium hydride (0.0308 g, 0.771 mmol) was added under an atmosphere of nitrogen. Benzenesulfonyl chloride (40, 0.0984 mL, 0.771 mmol) in 1 mL of tetrahydrofuran was added dropwise at room temperature under nitrogen. The reaction was stirred overnight at room temperature. The aqueous layer was separated and washed with ethyl acetate. The organic layers were combined and washed with 1 M aqueous sodium bicarbonate, water, then brine, dried over sodium sulfate, filtered and the filtrate concentrated under vacuum. The resulting material was purified by silica gel column chromatography, eluting with ethyl acetate and hexane. Appropriate fractions were combined and the solvents removed under vacuum to provide the desired compound (50, 0.121 g). MS (ESI) [M+H+]+=454.3.
