Reaction Steps

To 5-(1-benzenesulfonyl-1H-pyrrolo[2,3-b]pyridin-3-ylmethyl)-pyridin-2-ylamine (600, 150.0 mg, 0.41 mmol, prepared as described in Example 68, Scheme 185) in acetonitrile (12.5 mL) were added 3-fluoro-isocyanato-benzene (604, 61.6 mg, 0.45 mmol), 4-dimethylaminopyridine (10.0 mg, 0.082 mmol) and triethylamine (0.25 mL, 0.0018 mol). The reaction mixture was heated at 70° C. 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 a white solid (605, 0.100 g, 48.4%).
