Reaction Conditions

Reaction Steps

EDC.HCl (152 mg), HOBt (73 mg) and 4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)aniline (128 mg) were added to a solution of 1-benzyl-5-(4-fluorophenyl)-4-oxo-1,4-dihydropyridine-3-carboxylic acid (171 mg) in DMF (3 ml) at room temperature. The reaction mixture was stirred at 50° C. overnight. EDC.HCl (76 mg) and 4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)aniline (64 mg) were added to the reaction mixture at 50° C. The reaction mixture was stirred at 50° C. overnight. The reaction mixture was stirred at 80° C. overnight. The reaction mixture was returned to room temperature and diluted by adding water. The precipitated solid was collected by filtration. The resulting solid was purified by silica gel column chromatography [hexane:ethyl acetate=5:1->4:1->3:1->1:1 (v/v)] to give 112 mg of the title compound as a solid.
