실험 절차
To 5-Bromo-pyridine-2-carboxylic acid (4-chloro-phenyl)-amide (70, 0.50 g, 1.60 mmol) in tetrahydrofuran (20.0 mL), under an atmosphere of nitrogen at −78° C., tert-butyllithium (3.02 mL, 1.70M in Hexane) was added. After 20 minutes, 1-triisopropylsilanyl-1H-pyrrolo[2,3-b]pyridine-3-carbaldehyde (47, 0.39 g, 1.3 mmol, prepared as described in Example 18) in tetrahydrofuran (10.0 mL) was added to the reaction. The reaction was stirred at −78° C. for 1 hour, then allowed to warm to room temperature for minutes. The reaction was poured into water 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% ethyl acetate in hexane to give the compound as colorless oil (71, 100 mg, 14%). MS (ESI) [M+H+]+=535.3.
