A resealable tube was charged with 1-benzyl-4-benzyloxy-3-iodo-2-pyridone 3 (5.000 g, 11.98 mmol), acetonitrile (100 mL), and triethylamine (6.06 g, 8.35 mL, 59.9 mmol). Dichlorobis(triphenylphosphine)palladium (II) (0.841 g, 1.20 mmol) and 1-phenyl-2-(trimethylsilyl)acetylene were added and argon was bubbled through the solution. The tube was sealed and the mixture stirred at 100° C. for 4 h. The reaction mixture was concentrated to afford 7-benzyl-3-phenyl-2-(trimethylsilyl)furo[2,3-b]pyridin-4(7H)-one 4d as a brown oil. MS (MH+) 374.2; Calculated 373 for C23H23NO2Si.
