Reaction Steps

To a solution of 5-bromo-2-fluorobenzaldehyde (3.4160 g, 16.8 mmol) and DMAP (0.0256 g, 0.21 mmol, 0.012 equiv) in CH3CN (35 mL) was added TMSCN (1.8885 g, 19.0 mmol, 1.13 equiv) dropwise via a syringe under nitrogen at room temperature. After 3.75 h, the solvent was removed under reduced pressure. The crude product was directly used in the next step without further purification.
