To 5-(1-methyl-1H-pyrazol-4-yl)-1H-pyrrolo[2,3-b]pyridine (109, 100.0 mg, 0.51 mmol, prepared as described in Example 35) in methanol (30 mL) were added 2,6-dichloro-3-(2,2,2-trifluoro-ethoxy)-benzaldehyde (115, 154 mg, 0.56 mmol) and potassium hydroxide (596.0 mg, 10.62 mmol) under an atmosphere of nitrogen. The reaction was stirred at room temperature overnight. 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 2% to 25% methanol in dichloromethane to give the desired compound (116, 0.18 g, 75.7%).
