Versuchsvorschrift
3-Chloro-4-[(difluoromethyl)oxy]benzoic acid (D17; 0.28 g, 1.258 mmol) was stirred at room temperature with oxalyl chloride (0.220 mL, 2.52 mmol) and N,N-dimethylformamide (DMF) (0.05 ml) in dry dichloromethane (DCM) (5 ml) under nitrogen for 16 h. The solvent was evaporated in vacuo to give a yellow semi-solid (380 mg) which was used crude in the subsequent reaction D47.
