Reaction Steps

To 4-bromo-2-(tetrahydro-pyran-4-yloxy)-pyridine (0.2 g, 0.77 mmol) in DMSO (5 ml) (degassed by bubbling N2 through) was added 4,4,5,5,4′,4′,5′,5′-octamethyl-2,2′-bi-1,3,2-dioxaborolane (0.39 g, 1.55 mmol) and potassium acetate (0.27 g, 2.31 mmol). PdCl2ddpf (0.028 g, 0.04 mmol) was added, the reaction mixture again degassed and then heated at 100° C. for 5 h. The compound was passed through a C18 reverse phase chromatography column to afford desired product, used crude. MS: [MH]+ 224.
