Reaction Steps

((1R)-1-Phenylethyl)(5-nitro-2-(5-quinolyl)(4-pyridyl))amine. ((1R)-1-Phenylethyl)(2-bromo-5-nitro(4-pyridyl))amine (5.6g, 1.75 mmol)and 5-quinolineboronic acid (393 mg, 2.27 mmole) were dissolved in DMF (25 ml). Nitrogen gas was bubbled into solution for 2 min. Potassium carbonate (970 mg, 7.00 mmol) in water (5 mL) was then added followed by tetrakis(triphenylphosphine)palladium (0) (0.175 mmol). The solution was then heated to 85° C. under nitrogen for 1 h. The solution was condensed under reduced pressure and the crude product was diluted with ethyl acetate and filtered through a plug of silica-gel. The resultant filtrate was condensed under reduced pressure to afford the title compound (502 mg, 77%). MS (ESI) m/z 371 [M+1]+.
