Reaction Steps

To a mixture of 2′,5′-dimethyl-3,4,5,6-tetrahydro-2H-[1,4]bipyridinyl-4-ylamine (143 mg, 0.48 mmol), 2-[2-chloro-6-(4-chloro-benzyl)-pyrimidin-4-yl]-propan-2-ol (99 mg, 0.48 mmol), finely milled potassium carbonate (100 mg, 0.72 mmol) in dioxane (2 mL) was added under an argon atmosphere palladium(II) acetate (5 mg, 0.02 mmol) and 2-(dicyclohexylphosphino)biphenyl (17 mg, 0.05 mmol) and the reaction mixture was heated at 150° C. for 30 minutes. Concentration and purification by chromatography (SiO2, n-heptane/ethyl acetate/(ethyl acetate/triethylamine=95:5)=50:50:0 to 0:80:20) afforded the title compound (67 mg, 30%) as a light brown foam.
