Procedure

Oxalyl chloride (1.56 g, 1.1 ml, 12.32 mmol) is added to a stirring solution of 2-[4-(4-trifluoromethylphenoxy)phenoxy]propionic acid (2.00 g, 6.16 mmol), dimethylformamide (DMF; 4 drops) and ether (50 ml). The mixture is stirred at RT for 3 hours. Insoluble material is filtered off and solvent is removed in vacuo to give 2-[4-(4-trifluoromethylphenoxy)phenoxy]propionic acid chloride.
