Versuchsvorschrift

5-Chloro-3-iodo-1-triisopropylsilanyl-1H-pyrrolo[2,3-b]pyridine (144, 0.235 g, 0.541 mmol, prepared as described in Example 49) was dissolved in tetrahydrofuran (5 mL, 60 mmol). The solution was cooled to −25° C. After the addition of 2 M of isopropylmagnesium chloride in tetrahydrofuran (400 μL) the reaction was warmed to −10° C. with stirring. The reaction was cooled to −30° C. and 2-fluoro-5-methoxy-4-(1-methyl-1H-benzimidazol-2-ylmethoxy)-benzaldehyde (143, 0.170 g, 0.541 mmol) in 4 mL of tetrahydrofuran was added at once to the mixture. The reaction warmed to −10° C. and then evaporated to dryness. Ethyl acetate was added and the organic portion was washed with saturated sodium bicarbonate solution and brine, dried over anhydrous sodium sulfate and concentrated. Purification with silica gel flash chromatography with a gradient of ethyl acetate (5 to 80%) in hexanes gave the desired compound 145.
