Dimethylformamide → N-(5-Acetyl-2-fluorophenyl)acetamide

Participants

Reaction Steps

To a round, bottom flask was added 3-amino-4-fluoroacetophenone (Method 64, 1 g, 6.54 mmol) in DMF (15 ml), followed by the addition of acetyl chloride (0.56 ml, 7.84 mmol) and DIEA (2.3 ml, 13.08 mmol). The solution was set to stir at room temperature. The reaction appeared complete by TLC after 30 min. The reaction was then quenched with water and partitioned with EtOAc. The layers were cut, followed by an additional wash of the aqueous with EtOAc. The combined organic layers were dried over Na2SO4, filtered and concentrated in vacuo. The crude residue obtained (1.17 g), was used directly in the next step. 1H NMR (CDCl3) δ 8.94 (d, J=7.54 Hz, 1H) 7.71 (d, 1H) 7.43 (s, 1H) 7.15 (s, 1H) 2.56-2.60 (m, 3H) 2.21-2.28 (m, 3H).
