Versuchsvorschrift
In step 1-3, a solution of 3-(3-amino-6-chloropyridin-2-ylamino)benzonitrile (1.07 g, 4.38 mmol) and foramidine acetate (1.37 g, 13.1 mmol) in ethanol was refluxed for 3 hours. The reaction mixture was concentrated and purified to afford 3-(5-chloro-3H-imidazo[4,5-b]pyridin-3-yl)benzonitrile (1-3) as a yellow solid.
