Procedure

To 5-Pyridin-3-yl-1H-pyrrolo[2,3-b]pyridine (89, 750.0 mg, 0.003842 mol, prepared as in Example 17) in methanol (20.0 mL) were added 3-Benzyloxy-2,6-difluoro-benzaldehyde (526, 1.12 g, 4.5 mmol) and potassium hydroxide (1.50 g, 0.0267 mol) under an atmosphere of nitrogen. The reaction was stirred at room temperature overnight and then poured into water, acidified with 1N HCl to pH around 2 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 (527, 700 mg, 35%).
