Versuchsvorschrift
2,3-Dimethoxybenzoic acid (182 mg, 1 mmol) was treated with a solution of oxalyl chloride (1.5 mL of 2 M in dichloromethane, 3 mmol) and a catalytic amount of N,N-dimethylformamide. The reaction was stirred at ambient temperature for 2 hours. The excess oxalyl chloride was removed in vacuo to afford 2,3-dimethoxybenzoyl chloride.
Aufarbeitung
- customThe excess oxalyl chloride was removed in vacuo
