3-({[tert-butyl(dimethyl)silyl]oxy}methyl)-2-chloropyridine (1 g), tris(dibenzylideneacetone)-dipalladium(0) (89 mg), 1,1-bis(diphenylphosphino)ferrocene (108 mg), sodium tert-butoxide (559 mg), and 3-(methylamino)pyridine (629 mg) were combined, and 20 mL toluene was added. The mixture was heated 100 C under Ar for 16 h, then cooled to room temperature and filtered through celite, washing with CH2Cl2. The filtrate was concentrated and purified via flash chromatography to give 1.06 g of 3-({[tert-butyl(dimethyl)silyl]oxy}methyl)-N-methyl-N-pyridin-3-ylpyridin-2-amine.
