Participants

Reaction Steps

2-Fluoro-5-formyl-benzonitrile (5 g, 33.5 mmol) and CsF (51 mg, 0.335 mmol) in THF (10 mL) were treated with TMSCF3 (4.77 g, 33.5 mmol) at room temperature for 2 hours. The reaction was then treated with 4 N HCl (5 mL) and stirred at room temperature for 30 min. The solvent was removed and the residue was partitioned between ether and water. The organic layer was washed with brine, dried over anhydrous Na2SO4, filtered and concentrated to give the crude material, purified by silica gel column (hexanes:ethyl acetate 3:1) to afford the title compound as colorless solid (4.5 g, 61%).
