Reaction Steps

Combine 7-iodo-imidazo[1,2-a]pyridine (2.64 g, 10.82 mmol), ethynyl-triisopropyl-silane (3.61 mL, 16.23 mmol), copper (I) iodide (0.103 g, 0.541 mmol) and triethylamine (7.54 mL, 54.09 mmol) in 1,4-dioxane (50 mL). Bubble nitrogen through the mixture for five minutes. Add [1,1′-Bis(diphenyl-phosphino)ferrocene] dichloropalladium(II) (0.442 g, 0.541 mmol, 1:1 complex with dichloromethane). Attach a reflux condenser, and heat the mixture to 85° C., stir overnight (15 hours), and cool to room temperature. Filter the mixture through Celite® 521. Concentrate the solution in vacuo to a dark brown oil and use as is. MS(ES), m/z 299 (M+1).
