実験手順

Suspend 4-[4-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-phenyl]-N-(3-trifluoromethyl-phenyl)-butyramide (0.47 g, 1.15 mmol), 7-chloro-3-iodo-imidazo[1,2-a]pyridine (0.29 g, 1.05 mmol) and solid potassium carbonate (0.48 g, 3.45 mmol) in dioxane (4 mL) and water (2 mL). Deoxygenate the reaction contents with nitrogen for 10 minutes at room temperature. Add trans-dichlorobis(triphenylphosphine)palladium (II) (22 mg, 0.03 mmol) to the reaction. Fit a reflux condenser and heat the reaction to 105° C. over the weekend. Cool the reaction, dilute with dichloromethane and filter through Celite®. Concentrate the filtrate and then chromatograph on silica, using 0-3% methanol/ethyl acetate, to yield the product (301 mg, 57%). MS(ES), m/z 458 (M+1).
