To a solution of 1-benzyl-4-benzyloxy-3-iodo-1H-pyridin-2-one (1.00 g, 2.40 mmol), diisopropylethylamine, (0.51 mL. 2.88 mmol) and Pd(dppf)2Cl2/CH2Cl2 (0.20 g, 0.24 mmol) in DMF (10.0 mL) was slowly added 1-phenyl-2-(triethylsilyl)acetylene (1.50 g, 7.20 mmol) at room temperature under N2. The resulting reaction mixture was degassed and stirred at 108° C. under nitrogen overnight. The reaction was cooled down to room temperature, and the solvent was removed. The residue was dissolved in DCM (250 mL). The solution was washed with NaHCO3 (30×2 mL) and brine (30 mL). The organic layer was dried over MgSO4 and concentrated. The residue was purified by silica gel column chromatography, eluting with ethyl acetate/methanol/100/1, to give the title compound. MS (m/z), M+H+ 416.2.
