Following a reported procedure, 9 trimethylsilyl triflate (1.0 mL, 5.5 mmol, 1.1 equiv) was added to a suspension of 2-iodosylbenzoic acid (16) (1.32 g, 5.00 mmol, 1.00 equiv) in CH2Cl2 (15 mL) at room temperature. The resulting suspension was stirred for 3 h, followed by the drop wise addition of trimethyl(p-tolylethynyl)silane (17) (1.04 g, 5.50 mmol, 1.10 equiv). The resulting suspension was stirred for 6 h at room temperature. A saturated solution of NaHCO3 (20 mL) was then added and the mixture was stirred vigorously for 30 minutes. The mixture was extracted with H2O and DCM (3x20 mL), washed with brine, then dried over Na2SO4, filtered and evaporated under reduced pressure. The resulting solid was recrystalized in EtOAc:MeOH (2:1) (40 ml/gram). The solution was left to cool to RT overnight.. The crystal formed was filtered and dried under high vacuum to afford 2b (0.620 g, 1.71 mmol, 34%) as a white crystals. . Consistent with reported data. 9
