Procedure

To 3-nitrobenzaldehyde (534, 1.08 g, 7.17 mmol) in methanol (34 mL) was added 5-pyridin-3-yl-1H-pyrrolo[2,3-b]pyridine (89, 1.08 g, 5.52 mmol, prepared as described in Example 17) and potassium hydroxide (1.55 g, 27.6 mmol). The reaction was stirred at room temperature for four hours. The reaction was poured into water and extracted with ethyl acetate. The organic layer was washed with brine, dried over anhydrous sodium sulfate and concentrated. The mixture was purified by silica gel column chromatography eluting with 4% methanol in dichloromethane to provide two different compounds, a white solid (P-1399, R═H, 1.20 g, 63%) MS (ESI) [M+H+]+=347.2, and a light yellow solid (535, R=Me, 0.434 g, 22%).
