実験手順

To a solution of 1-benzenesulfonyl-5-chloro-3-iodo-1H-pyrrolo[2,3-b]pyridine (581, 0.420 g, 1.00 mmol) in tetrahydrofuran (15.0 mL) at −40° C. under nitrogen, isopropylmagnesium chloride (2.0 M in tetrahydrofuran, 0.49 mL) was added slowly. The reaction was allowed to warm to 5° C. over 70 minutes, then cooled to −40° C., followed by adding (2-fluoro-benzyl)-(5-formyl-pyridin-2-yl)-carbamic acid tert-butyl ester 579 in tetrahydrofuran (6.0 mL). The reaction was allowed to warm to room temperature over 1 hour, then poured into aqueous ammonium chloride, and extracted with ethyl acetate. The organic layer was dried over anhydrous sodium sulfate, and filtered. The filtrate was concentrated and purified by silica gel column chromatography eluting with 20% to 100% ethyl acetate in hexane to give the desired compound (582, 0.25 g, 41%). MS (ESI) [M+H+]+=623.1.
