To 5-chloro-1H-pyrrolo[2,3-b]pyridine (532, 0.092 g, 0.60 mmol) in methanol (15.0 mL) were added (5-formyl-pyridin-2-yl)-(6-methoxy-pyridin-3-ylmethyl)-carbamic acid tert-butyl ester (585, 0.240 g, 0.70 mmol, prepared according to the protocol of Example 17, Scheme 19, Steps 1-3, replacing 4-chlorobenzaldehyde 40 with 6-methoxy-pyridine-3-carbaldehyde in Step 1) and potassium hydroxide (1.2 g, 0.021 mol). The reaction was stirred at room temperature overnight, then 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% to 100% ethyl acetate in hexane to give the desired compound (586, 0.110 g, 37%).
