Reaction Steps

Combine 7-ethynyl-imidazo[1,2-a]pyridine (1.10 g, 7.74 mmol), copper (I) iodide (0.074 g, 0.387 mmol), and trimethylsilyl azide (1.53 mL, 11.61 mmol) in a 9:1 mixture of DMF:methanol (13.8 mL) in a pressure flask. Seal the flask with a Teflon screw cap and heat the reaction mixture to 100° C., stir overnight (15 hours), and cool to room temperature. Concentrate the mixture to dryness in vacuo. Slurry the resulting solid into dichloromethane and filter through Celite® 521. Concentrate the solution in vacuo to an orange solid. Purify by column chromatography (ethyl acetate→5% methanol in dichloromethane→8% methanol in dichloromethane) to afford product (0.82 g, 57%). MS(ES), m/z 186 (M+1).
