To a solution of 5-{[tert-butyl(dimethyl)silyl]ethynyl}-2-{[6-(morpholin-4-ylmethyl)pyridin-2-yl]amino}thiophene-3-carboxamide (435 mg, 0.95 mmol) in THF (15 mL) was added TBAF (1.0 M in THF, 2.38 mL, 2.38 mmol), and the reaction was stirred at room temperature for 6 h. The solution was diluted with water and extracted with EtOAc (2×). The organic extracts were dried over magnesium sulfate, filtered, combined with silica gel and evaporated. Flash chromatography (dry load, 0-10% MeOH/EtOAc) provided the title compound as a gray solid.
