Procedure

To 5-(1-benzenesulfonyl-5-chloro-1H-pyrrolo[2,3-b]pyridin-3-ylmethyl)-pyridin-2-ylamine (599, 80.0 mg, 0.20 mmol, prepared as described in Example 68, Scheme 185) in ethanol (2.0 mL) and acetic acid (0.10 mL, 0.0018 mol) were added 5-fluoro-pyridine-3-carbaldehyde (594, 62.7 mg, 0.50 mmol) and sodium cyanoborohydride on silica gel (1.200 mmol/g loading; 0.251 g, 0.30 mmol). The reaction was irradiated with microwave on 300 watts, 100° C. for 10 minutes. The reaction was poured into aqueous potassium carbonate 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 (601, 0.060 g, 59%).
