Reaction Steps

A mixture of 3-iodo-8-trifluoromethyl-6-(4-trifluoromethyl-phenyl)-imidazo[1,2-a]pyridine (8.36 g, 18 mmol), trimethylsilylacetylene (5.1 mL, 37 mmol), Et3N (7.66 mL, 55 mmol), PdCl2(PPh3)2 (64 mg, 0.5 mol %) and PPh3 (48 mg, 1 mol %) in THF (40 mL) was stirred for 10 min at 23° C. while being purged with Argon. Then CuI (10 mg, 0.3 mol %) was added.
