Procedure

Treat a solution of 5-difluoromethoxy-isophthalic acid dimethyl ester (2.7 g, 10.4 mmol) in methanol (35 mL) with 2 N NaOH (5.2 mL, 10.4 mmol) at room temperature for 12 h. Acidify to about pH=3 using 5 N HCl. Extract with ethyl acetate, wash the organic layer with water, saturated aqueous sodium chloride, dry (sodium sulfate) and concentrate to give the crude title product which is used in the next step without further purification.
