5-Iodo-N-(2-morpholinoethyl)pyridin-2-amine (0.82 g, 2.46 mmol), TMS acetylene (1.70 mL, 12.3 mmol), and triethylamine (0.69 mL, 4.92 mmol) were dissolved in dioxane (20 mL) and with nitrogen for about 15 min. Tetrakis(triphenylphosphine)palladium (142 mg, 0.12 mmol) and copper (I) iodide (47 mg, 0.25 mmol) were added before the reaction mixture was heated to 80° C. for 3.5 h. The reaction mixture was diluted with 100 mL EtOAc, washed with 50 mL saturated, aqueous NaHCO3, and dried over anhydrous Na2SO4. After purification by chromatography, the title compound was obtained. MS (ES+): 304 (M+H)+.
