HCID 27752812,4,5-Trifluoro-3-methoxybenzoyl chloride

Procedure

A mixture of 2,4,5-trifluoro-3-methoxybenzoic acid (154 mg, 0.75 mmol) and thionyl chloride (8 mL) is refluxed for 4 h. Excess thionyl chloride is removed in vacuo, and the remaining residue is used directly in the next synthetic step.
