実験手順

To a solution of 1-benzenesulfonyl-3-iodo-5-methoxy-1H-pyrrolo[2,3-b]pyridine (16, 1 equivalent) in 4.0 mL of tetrahydrofuran, isopropylmagnesium chloride (2.0 M in tetrahydrofuran, 1 equivalent) is added slowly at −50° C. The reaction is allowed to warm to 5° C. over 70 minutes, then cooled to −45° C. and (5-fluoro-2-methoxy-pyridin-3-ylmethyl)-(5-formyl-pyrimidin-2-yl)-carbamic acid tert-butyl ester (123, 0.78 equivalent) in 2.0 mL of tetrahydrofuran is added. The reaction is allowed to warm to room temperature over 1 hour, then poured into aqueous ammonium chloride and extracted with ethyl ether. 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 20-100% ethyl acetate in hexane. Appropriate fractions are combined and concentrated under vacuum to provide the desired compound.
