    • General Procedure for Fluorine Replacement A Schlenk flask was charged with the ethynyl derivative and anhyd THF. A solution of EtMgBr (1 M in THF) was then added dropwise and the mixture was stirred at 50°C for 2 h. The mixture was then added at 25°C via a cannula to a solution of 4a-c in anhyd THF. The mixture was stirred at 70°C for 16 h and the solvent was removed by rotary evaporation. The residue was treated with H 2O and extracted with CH2Cl2. The organic extracts were washed with H2O, and dried over MgSO4. The solvent was removed, and the residue was purified by chromatography. Compound 5a Prepared following general procedure from 4a (100 mg, 0.22 mmol, 1-ethynyltoluene (104 mg, 0.9 mmol, EtMgBr (0.41 mL, 0.41 mmol, 1 M in THF, THF (8 mL, Chromatography (silica gel, CH2Cl 2-cyclohexane, 30:70 to 50:50) gave 5a as a blue crystalline powder 60 mg, 42
