Versuchsvorschrift
3-Chloro-5-fluorobenzoic acid (400 mg, 2.3 mmol) was treated with a solution of oxalyl chloride (4.6 mL of 2.5 M in dichloromethane, 11.5 mmol) and a catalytic amount of N,N-dimethylformamide. The reaction was stirred at ambient temperature for 2.5 hours. The excess oxalyl chloride was removed in vacuo to afford 3-chloro-5-fluorobenzoyl chloride.
Aufarbeitung
- customThe excess oxalyl chloride was removed in vacuo
