tert-Butyl 4-(4-(azetidine-3-carboxamido)phenoxy)piperidine-1-carboxylate (4.97 g, 13.24 mmol), cesium carbonate (10.78 g, 33.1 mmol), 3-bromopyridine (1.307 ml, 13.24 mmol), (9,9-dimethyl-9H-xanthene-4,5-diyl)bis(diphenylphosphine) (0.764 g, 1.32 mmol) and bis(dibenzylideneacetone)palladium(0) (0.606 g, 0.662 mmol) were suspended in dioxane (50 ml), bubbled with nitrogen for 30 minutes and heated at 100° C. overnight. The mixture was filtered through a celite pad with dichloromethane washes and the filtrate was concentrated. Normal phase chromatography provided the title compound.
