Procedure

1-Ethyl-3-(5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-4-(4-(trifluoromethyl)thiazol-2-yl)pyridin-2-yl)urea (0.171 g, 0.39 mmol, Intermediate 17), ethyl 6-iodo-1-(2-methoxyethyl)-4-oxo-1,4-dihydroquinoline-3-carboxylate (0.155 g, 0.39 mmol, Intermediate 20), cesium carbonate (0.214 g, 0.66 mmol, Aldrich) and tris(dibenzylideneacetaone)palladium (0) (0.035 g, 0.04 mmol, Aldrich) or tetrakis(triphenylphosphine)palladium (0) (5 mol %, Strem) were combined in dioxane (2 mL)/water (0 mL) and heated to 100° C. The reaction mixture was stirred for 1 h. The reaction mixture was cooled to room temperature and then placed in an ice-bath. The resulting precipitate was collected by filtration and dried under vacuum to provide the desired product (0.090 g).
