Procedure

Dissolve N-Methyl-N-propyl-5-thiazol-2-yl-isophthalamic acid methyl ester (150 mg, 0.47 mmol) in methanol (6 mL). Add dropwise 2 N NaOH (0.3 mL) and stir overnight at room temperature. Acidify the mixture to about pH=6 by 5 N HCl and concentrate to near dryness. Dilute with ethyl acetate (20 mL) and wash the organic layer with saturated aqueous sodium chloride solution, dry (magnesium sulfate) and concentrate to give the title compound as an oil.
