In a 4 mL vial charged with a stir bar, 2,2-dimethyl-N-(5-methyl-1,3-thiazol-2-yl)propanamide (71 mg, 0.35 mmol) was added, followed by copper(I) trifluoromethanesulfonate benzene complex (35 mg, 0.07 mmol), 5-chloro-1,10-phenanthroline (30 mg, 0.14 mmol) and cesium carbonate (126 mg, 0.39 mmol). A loose cap with septum was placed on the vial and the vial was placed under vacuum in a vacuum oven for 30 minutes. The solid mixture was purged with nitrogen gas a couple of times. Then 1,3-dichloro-5-iodobenzene (115 mg, 0.42 mmol) dissolved in 1-methyl-2-pyrrolidinone (1.0 mL) was added to the solid mixture. The vial was capped and placed on a heater/stirrer and heated to 120° C. overnight. Then a 1 mL solution of concentrated ammonium hydroxide/water (1:2) was added. The reaction was filtered and concentrated to dryness. The residue was purified by reverse phase HPLC (C8, gradient 10-100% acetonitrile/water/0.1% trifluoroacetic acid).
