Reaction Steps

11.5 g (31.3 mmol) of tert-butyl-[2-(5-trimethylsilanylethynyl-thiophen-2-yl)-imidazo[1,2-a]pyridin-3-yl]-amine were dissolved in a mixture of MeOH (230 ml) and DCM (50 ml) and combined with 431 mg (3.13 mmol) of potassium carbonate The reaction solution was stirred at RT for 30 min and then combined with water (200 ml). The mixture was then extracted with DCM and the organic phase was washed with water and dried over MgSO4. After filtration and evaporation under a vacuum, 9.0 g (30.5 mmol, 97%) of tert-butyl-[2-(5-ethynyl-thiophen-2-yl)-imidazo[1,2-a]pyridin-3-yl]-amine were obtained.
