Following reported procedure, 9 Trimethylsilyl triflate (0.44 mL, 2.5 mmol, 1.1 equiv) was added to a suspension of 2-iodosylbenzoic acid (16) (0.589 g, 2.23 mmol, 1.00 equiv) in CH2Cl2 (6.8 mL) at RT The resulting suspension was stirred for 1 h, followed by the dropwise addition of ((3-fluorophenyl)ethynyl)trimethylsilane (21) (0.50 mL, 2.5 mmol, 1.1 equiv). The resulting suspension was stirred for 6 h at RT. A saturated solution of NaHCO3 (10 mL) was then added and the mixture was stirred vigorously for 30 minutes, resulting in a suspension. The mixture was extracted with H2O and DCM (3x10 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 and kept in fridge overnight. The crystal formed was filtered and dried under high vacuum to afford product 2f (384 mg, 1.05 mmol, 47% yield) as colorless crystals. Consistent with reported data. 9
