Acetyl chloride → HCID 67063052, compound

Participants

Reaction Steps

Acetyl chloride (3.12 g, 40 mmol) was added to a 0° C. solution of ethyl 2-(5-amino-4-fluoro-2-methylphenyl)-2-oxoacetate (9 g, 40 mmol) and Et3N (8.1 g, 80 mmol) in CH2Cl2 (80 mL). The resulting mixture was stirred at RT for 3 h. The solvent was removed under reduced pressure to give ethyl 2-(5-acetamido-4-fluoro-2-methylphenyl)-2-oxoacetate (10.7 g, 100% yield), which was used in the next step without further purification. 1H NMR (300 MHz, CDCl3): δ 8.71 (d, J=6.0 Hz, 1 H), 7.37 (brs, 1 H), 6.95 (d, J=8.7 Hz, 1 H), 4.39 (q, J=7.2 Hz, 2 H), 2.50 (s, 3H), 2.10 (s, 3 H), 1.40 (t, J=7.2 Hz, 3 H).
