実験手順

3-Iodo-1-triisopropylsilanyl-1H-pyrrolo[2,3-b]pyridine (635, 620 mg, 1.5 mmol, prepared as described in Example 45) was dissolved in tetrahydrofuran (15 mL) at −20° C. under an atmosphere of nitrogen. Isopropylmagnesium chloride (2.0 M in tetrahydrofuran, 840 μL) was added to the reaction. The reaction was stirred for 1.5 hours, during which the temperature rose to 5° C. The reaction was cooled to −20° C. 4-Benzyloxy-2-fluoro-5-methoxy-benzaldehyde (654, 250 mg, 0.9606 mmol) in tetrahydrofuran (5.0 mL) was added to the reaction. The reaction was stirred for 2.5 hours during which time the temperature rose to 5° C. The reaction was poured into water. The mixture was 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 2-25% ethyl acetate in hexane to provide compound as a white solid (655, 501 mg, 63%). MS (ESI) [M+H+]+=535.4.
