Reaction Steps

5-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrrolo[2,3-b]pyridine (1.01 g) was dissolved in tetrahydrofuran (10 ml). After the atmosphere was replaced with nitrogen, the solution was ice-cooled. 55% Sodium hydride (216 mg) was added and the mixture was stirred under ice-cooling for 20 minutes. Then, [2-(chloromethoxy)ethyl](trimethyl)silane (875 μl) was added and the mixture was stirred at room temperature for 15.5 hours. The reaction solution was diluted by adding water thereto, neutralized with 1 N hydrochloric acid (0.85 ml) and extracted with ethyl acetate three times. The organic layer was washed with water once and then with brine and dried over anhydrous sodium sulfate, and the solvent was evaporated. The brown oil was purified by silica gel column chromatography (developed with ethyl acetate-hexane) to give the title compound (691 mg) as a colorless oil.
