Procedure

To a solution of 7-benzenesulfonyl-5-iodo-4-methoxy-7H-pyrrolo[2,3-d]pyrimidine (42, 0.408 g, 0.983 mmol) in 4.0 mL of tetrahydrofuran at −50° C. under an atmosphere of nitrogen, isopropylmagnesium chloride (0.500 mL, 2.00 M in tetrahydrofuran, 1.00 mmol) was added slowly. The reaction was allowed to warm to 5° C. over 70 minutes, cooled to −45° C. and (2-chloro-benzyl)-(6-fluoro-5-formyl-pyridin-2-yl)-carbamic acid tert-butyl ester (19, 0.240 g, 0.658 mmol) in 2.0 mL of tetrahydrofuran was added. The reaction was allowed to warm to room temperature over an hour, 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 purified by silica gel chromatography eluting with 20-100% ethyl acetate in hexane. Appropriate fractions were combined and concentrated under vacuum to provide the desired compound (44, 0.400 g).
