Procedure
A tube was charged with 6′-bromo-5-[1-(2,6-dichloro-3-fluoro-phenyl)-ethoxy]-[3,3′]bipyridinyl-6-ylamine (92 mg, 0.20 mmol), 4-pyrrolidin-1-yl-piperidine (0.62 g, 4.0 mmol) and N-methylpyrrolidinone (0.8 mL). The tube was sealed and the mixture was heated at 80° C. overnight. The temperature was increased to 100° C. for 5.5 hours and then heating was ceased. The reaction was partitioned between ethyl acetate and water. The phases were separated and the aqueous phase was extracted with ethyl acetate. The combined organic phases were dried over MgSO4 and concentrated by rotary evaporation. The residue was purified by silica gel chromatography using gradient elution of dichloromethane, methanol, ammonium hydroxide to afford 5″-[1-(2,6-dichloro-3-fluoro-phenyl)-ethoxy]-4-pyrrolidin-1-yl-3,4,5,6-tetrahydro-2H-[1,2′;5′,3″]terpyridin-6″-ylamine (53 mg, 50%).
