Procedure

To 5-(2-methylsulfanyl-pyrimidin-5-ylmethyl)-7H-pyrrolo[2,3-d]pyrimidine (56, 1.20 g, 4.66 mmol) in 55.0 mL of N,N-dimethylformamide, sodium hydride (0.280 g, 7.00 mmol) was added. The reaction mixture was stirred at room temperature for 20 minutes, followed by addition of benzenesulfonyl chloride (40, 0.714 mL, 5.60 mmol). The reaction was stirred at room temperature for 3 hours, then poured into water and extracted with ethyl acetate. The organic layer was dried over sodium sulfate, filtered, and the filtrate was concentrated under vacuum. The resulting material was purified by silica gel column chromatography eluting with 20% ethyl acetate in hexane. Appropriate fractions were combined and the solvents removed under vacuum to provide the desired compound (57, 1.00 g).
