Versuchsvorschrift
To 6-fluoro-5-(5-methyl-1H-pyrrolo[2,3-b]pyridin-3-ylmethyl)-pyridin-2-ylamine (137, 3.99 g, 15.59 mmol) and 5-fluoro-1-methyl-2-oxo-1,2-dihydro-pyridine-3-carbaldehyde (33, 2.66 g, 17.15 mmol) in 50 mL of acetonitrile, triethylsilane (9.96 mL, 62.4 mmol) and trifluoroacetic acid (4.80 mL, 62.4 mmol) were added. The reaction was stirred at 80° C. for several hours, then concentrated under vacuum and the residue was taken up in ethyl acetate and poured into aqueous potassium carbonate. The organic layer was separated, concentrated under vacuum, and the residue purified by silica gel column chromatography, eluting with 0-5% methanol in dichloromethane. Appropriate fractions were combined and concentrated under vacuum, and the residue triturated with methanol to provide the desired compound (P-2156, 3.1 g, 7.84 mmol, 50.3% yield).
