実験手順

To a solution of 3-iodo-5-methyl-1-triisopropylsilanyl-1H-pyrrolo[2,3-b]pyridine (8, 0.43 g, 1.0 mmol) in 5 mL of tetrahydrofuran at −40° C. under nitrogen, isopropylmagnesium chloride (0.51 mL, 2.00 M in tetrahydrofuran, 1.0 mmol) is added slowly. The reaction is allowed to warm to −5° C. over 60 minutes, then cooled to −45° C., followed by addition of (6-ethoxy-pyridin-3-yl)-(6-fluoro-5-formyl-pyridin-2-yl)-carbamic acid tert-butyl ester (69, 0.06 g, 0.2 mmol) in 2.0 mL of tetrahydrofuran. The reaction is allowed to warm to room temperature over 2 hours, 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 20-100% ethyl acetate in hexane. Appropriate fractions are combined and concentrated under vacuum to provide the desired compound (70, 108.1 mg).
