Versuchsvorschrift

To a solution of 3-((trimethylsilyl)ethynyl) imidazo[1,2-b]pyridazine (28.46 g, 0.132 mol) in 200 mL of THF was added 145 mL (0.145 mol) 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 0-5% MeOH/DCM) to provide 17.84 g of product.
