Reaction Steps

To a solution of 3-((Trimethylsilyl)ethynyl)imidazo[1,2-a]pyrazine (0.15 g, 0.7 mmol) in 3.5 mL of THF was added 1.05 mL (1.05 mmol) of tetrabutylammonium fluoride (1.0M in THF) at ambient temperature. The solution was stirred for 15 min, concentrated, and the crude product purified by silica gel flash chromatography (eluted with 50% EtOAc/hexanes) to provide 0.078 g of product.
