Reaction Steps

To 5-iodo-4-(2-methoxy-ethoxy)-7H-pyrrolo[2,3-d]pyrimidine (25, 3.67 g, 11.5 mmol) in 60.0 mL of tetrahydrofuran under an atmosphere of nitrogen, sodium hydride (506.0 mg, 12.65 mmol) is added. The reaction is stirred at room temperature for 20 minutes, then benzenesulfonyl chloride (26, 1.614 mL, 12.65 mmol) is added. The reaction is stirred at room temperature for 30 minutes, then poured into water and extracted with ethyl acetate. The organic layer is dried over sodium sulfate, filtered and the filtrate concentrated under vacuum. The resulting material is purified by silica gel column chromatography, eluting with 15-100% ethyl acetate in hexane. Appropriate fractions are combined and concentrated under vacuum to provide the desired compound (27, 4.50 g). MS (ESI) [M+H+]+=460.0.
