Procedure

A mixture of 3-iodo-5-(5-methyl-pyridin-2-yl)-benzoic acid ethyl ester (367 mg, 1 mmol), 4-isopropyl-[1,2,3] thiadiazole (640 mg, 5 mmol), palladium II tetrakis(triphenylphosphine) (35 mg, 0.03 mmol) and potassium acetate (196 mg, 2 mmol) in 10 mL of DMF was warmed to 120° C. and stirred for 16 hours. The reaction mixture was cooled and transferred directly onto a silica column and purified by liquid chromatography (0% to 10% EtOAc/hexanes) to give 250 mg of 3-(4-isopropyl-[1,2,3] thiadiazol-5-yl)-5-(5-methyl-pyridin-2-yl)-benzoic acid ethyl ester, MS (M+H)=368.
